* Only install yum-utils if needed (b/c we're going to use repoquery)
* Add a warning message explaining that why slower repoquery was used
rather than yum API.
The message there is that Yum API prints an error message if the
rhn-plugin is in use and no rhn-certificate is available. So instead of
using repoquery in preference always here we use repoquery in preference
if the rhn-plugin is enabled.
The ordering of disabling/enabling yum repositories matters, and
the yum module was mixing and matching the order. Specifically,
when yum-utils isn't installed, the codepath which uses the yum
python module was incorrectly ordering enabling and disabling.
The preferred order is to disable repositories and then enable them
to prevent clobbering. This was previously discussed in
ansible/ansible#5255 and incompletely addressed in 0cca4a3.
There is no call to yum_base using 'cachedir' argument, so
while it work fine from a cursory look, that's useless code,
and so should be removed to clarify the code.
Using the rpm module prevent a uneeded fork, and permit
to skip the signature checking which slow down a bit the
operation, and which would be done by yum on installation
anyway.
Yum does not always update to latest package version unless metadata cache has expired. By runing yum makecache, we ensure the metadata cache has been updated.
