Merge branch 'display_prefix_on_new' into 'master'

Display prefix on new

When a client creates a new database or user which has prefix, prefix is not displayed until is created or error is returned. For clients, it's possible to display real prefix if CLIENTID or CLIENTNAME is used, if DOMAINID is used it will be displayed like [DOMAINID]. For reseller or admins, [CLIENTID], [CLIENTNAME] and [DOMAINID] will be displayed if client or domain is not selected.
