Add an optional --release parameter to subcloud add and reinstall
commands to enable release optionality in subcloud add and subcloud
reinstall.
Test Plan:
1. Verify successful subcloud add which includes remote install with
specified (previous/current) release
2. Verify successful subcloud reinstall with the specified
(previous/current) release
3. Verify the subcloud is successfully installed with the active
release when the release parameter is absent
4. Verify the subcloud is successfully reinstalled with the active
release when the release parameter is absent
5. Verify the subcloud install request was rejected
when the software_version in the install_values doesn't
match the specified release
6. Verify the subcloud install/reinstall request was rejected
when the kubernetes_version value specified in the subcloud bootstrap
yaml file doesn't match the value of the fresh_install_k8s_version of
the specified previous release
