[patch] MaaS: mcp.rsa.pub to auth keys via pillar

Drop one questionable patch responsible for MaaS node authorized
keys to include mcp.rsa.pub by reading the contents of authorized
keys on mas01, assuming mcp.rsa.pub will be on the first line.

Instead, export the contents of the public key using a shell env
var during deploy, which gets expanded via maas_pdf j2 template
into a reclass param, leveraging existing salt-formula-maas sshprefs
mechanism for delivering the key to MaaS.

Since we require the public key to exist before expanding templates,
move `generate_ssh_key` call outside the current infrastructure
handling block, allowing it to execute during all `deploy.sh` calls,
even for dry-runs.

-Subject: [PATCH] maas: region: use authorized_keys 1st entry
-
-MaaS custom py modules accepts the "sshprefs" variable via pillar,
-however we want to read it from ~ubuntu/.ssh/authorized_keys.
-
-Bypass the py module and call MaaS CLI directly, passing the first
-authorized key, which should be mcp.rsa.pub.
