Add --enforce-server-name-as-hostname to override the hostname
Allow to override any potential `hostname` in the Ignition associated with the `ServerBootConfiguration`. The result will be a `<config-name>-mutated` Ingition `Secret` which will be referenced in the `IPXEConfiguration` resource in order to prepare the correct ignition for the network boot process.
