Hashicorp Consul service mesh support

Request for supporting Hashicorp Consul service mesh from Kore Wireless.

From customer:

I was originally working with you over the couchbase forums (https://forums.couchbase.com/t/couchbase-helm-chart-and-hashicorp-consul-service-mesh/31682/5) . I have been working on implementing service mesh at my company for some time now and I am working on enabling and documenting use for currently deployed systems. If any testing or anything is needed I can definitely make time available.

Just wanted to say thank you for taking time to look into this and forward my company information. https://www.korewireless.com/

The annotations can be added via the CRD and Helm. Need to confirm this is all that is required.

For Helm:

cluster:

  servers:

    default:

      pod:

        metadata:

          annotations:

            consul.hashicorp.com/connect-inject: "true"   

            consul.hashicorp.com/connect-service: couchbase-test

For the standard CRD, this just gets nested into the appropriate bit of the server section.
