UPSTREAM: <carry>: Provide default NMState CR

Currently, admins have to install the NMState in two steps.  First they
have to install the operator and then navigate to the operator menu to
create an NMState CR.

With this patch, these two are merged into a single step where while
installing NMState operator, user will be asked to create the CR since
it is required. That then immediatelly triggers deployment of NMState
operands as a part of the NMState operator installation.
