Allow clones to specify master and replica ports and security options
Removed -clone_start_tls option and subsumed it into -replicationSecurity.
Refactored DatabasePanel parameter verification code to allow it to be
used in both update() and validate(). Added new parameters to pkisilent
and databasepanel.vm.
Also fixed cloning error when master uses localhost.
This is the second of the split patches. It also addresses issues found
by Endi in review.
Please review.
