Code Issues Proposed changes

Drop service* tables only if they exist

Browse Source 
Tables servicedefinitions and servicetypes are not used by neutron but
created using db migration tool. If quantum-server in grizzly was
started without using migration tool then tables mentioned above are not
created. During migration from grizzly to havana alembic attempts to
drop these unused tables. This patch uses "IF EXISTS" clause when
dropping mentioned tables.
