Move Managed Entries into their own container in the replicated space.

Repoint cn=Managed Entries,cn=plugins,cn=config in common_setup
Create: cn=Managed Entries,cn=etc,$SUFFIX
Create: cn=Definitions,cn=Managed Entries,cn=etc,$SUFFIX
Create: cn=Templates,cn=Managed Entries,cn=etc,$SUFFIX
Create method for dynamically migrating any and all custom Managed Entries
from the cn=config space into the new container.
Separate the connection creation during update so that a restart can
be performed to initialize changes before performing a delete.
Add wait_for_open_socket() method in installutils
