[Manila] Add new experimental job

Manila project is going to test its APIs using dummy driver
that does not really provide resources and just simulates
share driver behaviour.

For this we need to have separate tempest job, without any other
OpenStack projects, just manila.
Therefore, add such, make it non-voting and experimental until
appropriate feature merged in manila and becomes stable.
