(#8062) Consider package epoch version when comparing yum package versions

[jhelwig]

By including the epoch version in the version returned as the "latest"
available, we can now properly consider package updates where only the
epoch version has changed.

There's a comment in the install method "XXX: We don't actually deal with epochs here."

Is this wrong now (should be removed) or is it still the case for install and does that affect the functionality of this patch?

I'll take it out. I don't think we actually need to do anything special since yum can understand packages with epochs in either name-epoch:ver-rel.arch or epoch:name-ver-rel.arch form, and the former should just work if people wish to specify the epoch as part of the ensure value instead of as part of the name.

package { 'foo':
  ensure => '1:1.2.3',
  provider => 'yum',
}

vs

package { '1:foo':
  ensure => '1.2.3',
  provider => 'yum',
}
