seven-beep a97a54dc30 Provide granular noop for ssh configuration (#789)
* Provide granular noop for shh configuration

We would like to have more fine grained options on applying or not specific configurations.

This commit let the user choose to noop some configuration with a few new
boolean variables.

Motivation for theses options are we may configure ourselves some (ssh host key
regeneration in a templating system) or we are not ready for others (ssh_kex
will break dist-upgrades, letting the operator without ssh).

* Provide granula noop for ssh configuration

We would like to have more fine grained options on applying or not specific configurations.

This commit let the user choose to disable configurations for `ssh_host_key_config`,
`ssh_ciphers_config`, `ssh_host_key_config`, `ssh_macs_config` by setting them
to False.

Motivation for theses options are we may configure ourselves some (ssh host key
regeneration in a templating system) or we are not ready for others (ssh_kex
will break dist-upgrades, letting the operator without ssh).
