[common] Add template tests to cookbook

[Federico Gimenez]

We need chefspec tests to assert the contents of the templates. Ideally we need to test conditional logic is handled properly in the templates and default attribute values.

    Added missing tests and checked existing ones

    Some of the tests have been modified to set the implied
    attributes to known values before verifying the
    expectations. The ceph.client.keyring.erb template has
    been deleted, any recipe was using it.
