Implement replica promotion functionality

This patch implements a new flag --promote for the ipa-replica-install command
that allows an administrative user to 'promote' an already joined client to
become a full ipa server.

The only credentials used are that of an administrator. This code relies on
ipa-custodia being available on the peer master as well as a number of other
patches to allow a computer account to request certificates for its services.

Therefore this feature is marked to work only with domain level 1 and above
servers.
