Add ability to change apt/yum package state

The current method of installing the distribution packages required is
set in the tasks and cannot be changed by a deployer.

Currently the apt task always installs the latest package. This results
in unexpected binary changes when a deployer may simply be trying to
execute a configuration change.

This patch adds the ability for a deployer to change the desired state
so that the results are predictable.

features:
- The memcached_server role now supports the ability to configure whether
apt/yum tasks install the latest available package, or just ensure
that the package is present. The default action is to ensure that
the latest package is present. The action taken may be changed to
only ensure that the package is present by setting
``memcached_package_state`` to ``present``.
upgrade:
- The memcached_server role always checks whether the latest package is
installed when executed. If a deployer wishes to change the check to
only validate the presence of the package, the option
``memcached_package_state`` should be set to ``present``.
