Remove dynamic keys from SSH Secrets Engine (#18874)
* Remove dynamic keys from SSH Secrets Engine

This removes the functionality of Vault creating keys and adding them to
the authorized keys file on hosts.

This functionality has been deprecated since Vault version 0.7.2.

The preferred alternative is to use the SSH CA method, which also allows
key generation but places limits on TTL and doesn't require Vault reach
out to provision each key on the specified host, making it much more
secure.
