feat: (Un)install DevWorkspaceRouting CRD during during (un)installation using operator.

[metlos]

What does this PR do?

This creates the DevWorkspaceRouting CRD during the installation with che-operator and uninstalls
it when deleting the cluster.

DevWorkspaceRouting will become a prerequisite of che-operator once the devworkspace-che-operator is merged into the che-operator codebase.

Note that this PR depends on eclipse-che/che-operator#894.

I'm closing this in favor of a design where che-operator will be still in charge of the installation of DWR and will have alternative watch sets based on the CRD presence in the cluster, as discussed with @sleshchenko.
