Installation guide needs chapter on adding database services (trove)

[Laurel Michaels]

The installation guide does not have info on how to add database services/trove. We need a chapter on how to do this, similar to the other chapters that describe how to add services (compute, networking, orchestration and so on).

    Add info on how to add Database service (Trove)

    The install guide did not have a chapter on how to add the
    Database service. Created one with the following sections:
    overview, install, verify.

    This draft reflects the fact that some technical issues are still
    being worked out:

    -- image creation questions. Before you can use Trove, you need to
    create an image for each flavor of database you want to have
    (MySQL, MongoDB, etc.) The appropriate level of documentation
    for this step is still under discussion and has not yet been
    determined.
