Remove the use of uuid in the directory server instance name.

The use of a uuid for the DS instance name is overkill and it is a real
pain. This patch will use ipa-realm-name instead (resulting in something
like slapd-EXAMPLE-COM). All periods are converted to "-" because the DS
can't handle periods in server ids.
