This updates some user and group queries to use machinery.

Notable changes include

• Removal of the command list users and replaces it with list group-users. This command works best if provided the group name, but if not provided will attempt to get all groups and members. Not currently recommended for large lagoon installations.
• Addition of list user-groups which if provided an email address will return the groups the user is in.
• Addition of list all-users which will return all users within Lagoon (even those that are not in any groups) but does not return any information about the groups the user is in, use the list user-groups command for specific users.

All of these commands are RBAC wrapped, if you use these commands and get a permission denied, this is because you do not have permission to do the requested action.

• list user-groups is scoped to self, and platform. You can't view another users groups, only your own.
• list all-users is platform only
• list group-users is scoped to groups you are a member of for a specific group, or platform for all groups
