Adds bigip_vcmp_guest module (#33024)

This module can be used to manage guests on a vCMP provisioned BIG-IP. vCMP is a hardware-only feature, therefore this module cannot be used on the VE editions of BIG-IP.

+module: bigip_vcmp_guest
+short_description: Manages vCMP guests on a BIG-IP
+description:
+  - Manages vCMP guests on a BIG-IP. This functionality only exists on
+    actual hardware and must be enabled by provisioning C(vcmp) with the
+    C(bigip_provision) module.
+version_added: "2.5"
+options:
+  name:
+    description:
+      - The name of the vCMP guest to manage.
+    required: True
+  vlans:
+    description:
+      - VLANs that the guest uses to communicate with other guests, the host, and with
+        the external network. The available VLANs in the list are those that are
+        currently configured on the vCMP host.
+      - The order of these VLANs is not important; in fact, it's ignored. This module will
+        order the VLANs for you automatically. Therefore, if you deliberately re-order them
+        in subsequent tasks, you will find that this module will B(not) register a change.
+  initial_image:
+    description:
+      - Specifies the base software release ISO image file for installing the TMOS
+        hypervisor instance and any licensed BIG-IP modules onto the guest's virtual
+        disk. When creating a new guest, this parameter is required.
+  mgmt_network:
+    description:
+      - Specifies the method by which the management address is used in the vCMP guest.
+      - When C(bridged), specifies that the guest can communicate with the vCMP host's
+        management network.
+      - When C(isolated), specifies that the guest is isolated from the vCMP host's
+        management network. In this case, the only way that a guest can communicate
+        with the vCMP host is through the console port or through a self IP address
+        on the guest that allows traffic through port 22.
+      - When C(host only), prevents the guest from installing images and hotfixes other
+        than those provided by the hypervisor.
+      - If the guest setting is C(isolated) or C(host only), the C(mgmt_address) does
+        not apply.
+      - Concerning mode changing, changing C(bridged) to C(isolated) causes the vCMP
+        host to remove all of the guest's management interfaces from its bridged
+        management network. This immediately disconnects the guest's VMs from the
+        physical management network. Changing C(isolated) to C(bridged) causes the
+        vCMP host to dynamically add the guest's management interfaces to the bridged
+        management network. This immediately connects all of the guest's VMs to the
+        physical management network. Changing this property while the guest is in the
+        C(configured) or C(provisioned) state has no immediate effect.
+    choices:
+      - bridged
+      - isolated
+      - host only
+  delete_virtual_disk:
+    description:
+      - When C(state) is C(absent), will additionally delete the virtual disk associated
+        with the vCMP guest. By default, this value is C(no).
+    default: no
+  mgmt_address:
+    description:
+      - Specifies the IP address, and subnet or subnet mask that you use to access
+        the guest when you want to manage a module running within the guest. This
+        parameter is required if the C(mgmt_network) parameter is C(bridged).
+      - When creating a new guest, if you do not specify a network or network mask,
+        a default of C(/24) (C(255.255.255.0)) will be assumed.
+  mgmt_route:
+    description:
+      - Specifies the gateway address for the C(mgmt_address).
+      - If this value is not specified when creating a new guest, it is set to C(none).
+      - The value C(none) can be used during an update to remove this value.
+  state:
+    description:
+      - The state of the vCMP guest on the system. Each state implies the actions of
+        all states before it.
+      - When C(configured), guarantees that the vCMP guest exists with the provided
+        attributes. Additionally, ensures that the vCMP guest is turned off.
+      - When C(disabled), behaves the same as C(configured) the name of this state
+        is just a convenience for the user that is more understandable.
+      - When C(provisioned), will ensure that the guest is created and installed.
+        This state will not start the guest; use C(deployed) for that. This state
+        is one step beyond C(present) as C(present) will not install the guest;
+        only setup the configuration for it to be installed.
+      - When C(present), ensures the guest is properly provisioned and starts
+        the guest so that it is in a running state.
+      - When C(absent), removes the vCMP from the system.
+    default: "present"
+    choices:
+      - configured
+      - disabled
+      - provisioned
+      - present
+      - absent
+  cores_per_slot:
+    description:
+      - Specifies the number of cores that the system allocates to the guest.
+      - Each core represents a portion of CPU and memory. Therefore, the amount of
+        memory allocated per core is directly tied to the amount of CPU. This amount
+        of memory varies per hardware platform type.
+      - The number you can specify depends on the type of hardware you have.
+      - In the event of a reboot, the system persists the guest to the same slot on
+        which it ran prior to the reboot.
+notes:
+  - Requires the f5-sdk Python package on the host. This is as easy as pip
+    install f5-sdk.
+  - This module can take a lot of time to deploy vCMP guests. This is an intrinsic
+    limitation of the vCMP system because it is booting real VMs on the BIG-IP
+    device. This boot time is very similar in length to the time it takes to
+    boot VMs on any other virtualization platform; public or private.
+  - When BIG-IP starts, the VMs are booted sequentially; not in parallel. This
+    means that it is not unusual for a vCMP host with many guests to take a
+    long time (60+ minutes) to reboot and bring all the guests online. The
+    BIG-IP chassis will be available before all vCMP guests are online.
+requirements:
+  - f5-sdk >= 3.0.3
+  - netaddr
