  1. Prepare for hubless env 

    To support an environment without a hub we need different flows when a
hub is available and not. Refactor the code to make it easy to support
this case.

  2. Support hubless environment in ramenctl 

    If environment does not have a hub:

- `ramenctl deploy` skips hub deployment
- `ramenctl undeploy` skips the hub deployment
- `ramenctl config` installs the s3 secret and
  ramen-dr-cluster-operator-config map on the dr clusters.
- `ramenctl unconfig` delete the s3 secrets from the dr clusters.

  3. Add regional dr environment without a hub 

    For testing kube object projection and recipes in an environment without
a hub. This is not really supported but we know about some users using
this topology, and having a test environment makes it easier to support
them and make sure we don't break them by mistake.

This environment is very similar to regional-dr.yaml, with these
changes:

- The hub cluster was removed
- ocm components were removed, since there is no hub
- submariner is deployed at the end instead of of running on the hub at
  the start of the deployment.

Because we run submariner at the end, and it takes about 140 seconds to
deploy and run the self test, starting this environment is slower than
the full regional-dr environment.

An alternative is to remove submariner and volsync from this
environment, and disable volsync in ramen config when a hub is not
available.

Example run:

    $ drenv start envs/regional-dr-hubless.yaml
