Add structs and fields to support the Nomad Pools Governance Enterprise feature of controlling node pool access via namespaces. Nomad Enterprise allows users to specify a default node pool to be used by jobs that don't specify one. In order to accomplish this, it's necessary to distinguish between a job that explicitly uses the `default` node pool and one that did not specify any. If the `default` node pool is set during job canonicalization it's impossible to do this, so this commit allows a job to have an empty node pool value during registration but sets to `default` at the admission controller mutator. In order to guarantee state consistency the state store validates that the job node pool is set and exists before inserting it.
