Description

When provisioning a cluster via a blueprint, there currently is a restriction that a host may only be associated with a single host group. If a user attempts to map a host to multiple host groups, strange errors are reported back to the user which do not explain the problem.

This work will validate that a host is only mapped to one host group early and will provide a good error message to the user if there is an attempt to map multiple host groups to a host.

{
"status" : 400,
"message" : "A host may only be mapped to a single host group at this time. The following hosts are mapped to more than one host group: [john2.novalocal]"
}
