* yum - only instantiate YumBase once
Previously, this code was re-instantiating the `YumBase` object
many times which is unnecessary and slow. However, we must do it
twice in the `state: absent` case because the `yumSack` and
`rpmSack` data of the previously instantiated object becomes
invalid and is no longer useful post transaction when we verify
that the package removal did in fact take place. Also, this patch
removes the repetitive re-processing of enable/disable of repos in
various places.
Here's a display of the speed increase against a RHEL7 host:
```yaml
- hosts: rhel7
remote_user: root
tasks:
- name: Install generic packages
yum:
state: present
name:
- iptraf-ng
- screen
- erlang
- name: Remove generic packages
yum:
state: absent
name:
- iptraf-ng
- screen
- erlang
```
