apt cache not updated after pin or repo additions

[Jesse Pretorius]

Whenever we add a repository or pinning preferences we should ensure that the apt cache is updated.

Currently we get failures when the mariadb packages try to install. This happens because the pinning has not yet taken affect and because apt doesn't think that it has packages available for the installation to complete properly.

Example errors:

No package matching 'mariadb-galera-server-5.5' is available

The following packages have unmet dependencies:
 mariadb-client : Depends: mariadb-client-5.5 (= 5.5.41+maria-1~trusty) but 5.5.41-1ubuntu0.14.04.1 is to be installed
 mariadb-galera-server-5.5 : Depends: mariadb-client-5.5 (>= 5.5.41+maria-1~trusty) but 5.5.41-1ubuntu0.14.04.1 is to be installed

    Update apt cache after adding repos or pinning

    This patch implements a forced apt cache update after a new apt
    repository is added, or any apt pinning is implemented.

    This ensures that apt is sure about what packages are available to it,
    and which packages/repositories should be preferred above others.

[OpenStack Infra (hudson-openstack)]

Change abandoned by Jesse Pretorius (<email address hidden>) on branch: master
Review: https://review.openstack.org/158681
Reason: The ansible module apt_repository has the default setting of 'update_cache: yes' which handles the equivalent of 'apt-get update' after the repository is added, so this is not required.

    Reorder common apt repo tasks

    An apt cache update was being initiated after the apt package pinning
    occured, but before apt repos were put in place. The order has changed
    so that both apt package pinning and an apt cache update occur after
    repos have been configured.
