#2055: Do not allow creating a container with same name. hawtio uses this api directely so it failed this check.
#2275: Create container name should only accept lower case name as that avoids creating duplicate names where the difference is only the case in the name. Also cloud environments do not like mixed case naming as they map the name to hostname.
Removed @deprecated from fabric mbean api as these operations is in use by hawtio
