Unit name issue with SFTP command.

[Cory Johns]

You can get the full unit name with:

    unit_name = d.sentry['ibm-db2'][0].info['unit_name']
    d.action_do(unit_name, ...)

We should perhaps consider moving action_do to the UnitSentry so that it
could instead be called as:

   d.sentry['ibm-db2'][0].action_do(...)
