Change cm to retrieve credentials (if available) regardless of cluster status

[sbostick]

As an end user of cm cli I want to retrieve managed cluster credentials, thus:

cm create cc clusterpool-sno-1 sno-1
cm get cc sno-1
cm use cc sno-1
oc get nodes

Alternatively:

cm get cc sno-1 --creds --timeout 1

Currently cm checks cluster state but due to HIVE-1743 the cluster state might be misidentified as Resuming. In this case cm aborts before attempting to retrieve the credentials.

A workaround is available to retrieve credentials:

oc extract -n clusterpool-sno-1-bxtjn secret/sno-1-g5pml-admin-password --to=-
oc extract -n clusterpool-sno-1-bxtjn secret/sno-1-g5pml-admin-kubeconfig --keys=kubeconfig --to=-

See also issues/247 related to KUBECONFIG creds management. Both issues are applicable to internal automation using ACM+Hive, for example compliance, interop, and scale testing, and related to credentials retrieval and management. Both really useful features for automation.
