Subject: [PATCH 1/2] rhel/cloud.cfg: remove ssh_genkeytypes in settings.py and
 set in cloud.cfg

RH-MergeRequest: 16: rhel/cloud.cfg: remove ssh_genkeytypes in settings.py and set in cloud.cfg
RH-Commit: [1/1] 67a4904f4d7918be4c9b3c3dbf340b3ecb9e8786
RH-Bugzilla: 1970909

Currently genkeytypes in cloud.cfg is set to None, so together with
ssh_deletekeys=1 cloudinit on first boot it will just delete the existing
keys and not generate new ones.

Just removing that property in cloud.cfg is not enough, because
settings.py provides another empty default value that will be used
instead, resulting to no key generated even when the property is not defined.

Removing genkeytypes also in settings.py will default to GENERATE_KEY_NAMES,
but since we want only 'rsa', 'ecdsa' and 'ed25519', add back genkeytypes in
cloud.cfg with the above defaults.

Also remove ssh_deletekeys in settings.py as we always need
to 1 (and it also defaults to 1).
