Refactors the process used to build the Datadog core integrations to
be more easily extensible with integrations other than the ones built
and installed by default.
Documentation has been added in relevant parts of the module to
describe how the process works.
As a high-level overview:
The `datadog-integrations-core` attribute in the top-level package set
now accepts an extra parameter.
This parameter is an attribute set where each key is the name of a
Datadog integration as it appears in Datadog's integrations-core
repository[1], and the value is a function that receives the Python
package set and returns the required dependencies of this integration.
For example:
datadog-integrations-core {
ntp = (ps: [ ps.ntplib ]);
};
This would build the default integrations and, additionally, the `ntp`
integration.
To support passing the modified Python environment to the
datadog-agent itself, the `python` key has been moved inside of the
derivation which means that it will be made overridable.
This relates to NixOS/nixpkgs#40399.

DataDog have adopted a subtle naming convention:
- dd-agent refers to the v5 Python implementation
- datadog-agent refers to the v6 golang implementation
As per project's README:
> Recent systems can resolve IPv6 host names using getaddrinfo(). This
> primitive is not present in all libcs and does not work in all of
> them either. Support in glibc was broken before 2.3. Some embedded
> libs may not properly work either, thus, support is disabled by
> default, meaning that some host names which only resolve as IPv6
> addresses will not resolve and configs might emit an error during
> parsing. If you know that your OS libc has reliable support for
> getaddrinfo(), you can add USE_GETADDRINFO=1 on the make command
> line to enable it. This is the recommended option for most Linux
> distro packagers since it's working fine on all recent mainstream
> distros. It is automatically enabled on Solaris 8 and above, as it's
> known to work.
Without this option, it is not possible for HAProxy to solve IPv6-only
names. This option is enabled in Debian builds without any notable
adverse effect.
