Separate the spec.name and meta.name from the Helm template.

Currently we have the following:

buckets:

  # A bucket to create by default

  name-of-meta-name:

    # Kind of bucket

    kind: CouchbaseBucket

    # Name of the bucket

    name: name-of-spec-name

Per the CouchbaseBucket resource here
https://docs.couchbase.com/operator/current/reference-couchbasebucket.html

The meta.name and spec.name should be separate, where meta.name is the resource's name, and the spec.name is the name that shows in the UI.

Currently with the Helm chart, both of these names are the meta.name, and the name itself gets overwritten by spec.name. We should separate these two like the standard CouchbaseBucket resource.
