support updating template stores using cyctl

[petar-cvit]

Is your feature request related to a problem? Please describe.
cyctl can currently create, list and delete template stores. It would be useful to update template stores using cyctl as well.

The command invocation should look like this:

cyctl update templates <templates-name> --path=<path> --repo=<repo> --version=<version> --icon=<icon>

repo, path, version, and icon are all optional, but at least one of them needs to be set. Flags update the following values in a template store object:

• repo - spec.repo
• path - spec.path
• version - spec.version
• icon - metadata.annotations.cyclops-ui.com/icon

When the subcommand is invoked, it should fetch the template store, update its values and update it in the cluster.
