[PATCH 0/3] Enable the setting of a kernel module parameter from nfs.conf

This is a tweak of the patch set Alice Mitchell posted last July [1].
It enables the setting of the nfs4_unique_id kernel module
parameter from /etc/nfs.conf.

Things I tweaked:

* Introduce a new [kernel] section in nfs.conf which only
contains the nfs4_unique_id setting... For now...

* nfs4_unique_id can be set to two different values

- nfs4_unique_id = ${machine-id} will use /etc/machine-id
as the unique id.
- nfs4_unique_id = ${hostname} will use the system's hostname
as the unique id.

* The new nfs-config systemd service need to be enabled for the
/etc/modprobe.d/nfs.conf file to be created with
the "options nfs nfs4_unique_id=" set.

I see this patch set is not a way to set the nfs4_unique_id
module parameter... I see it as a beginning of a way to set
all module parameters from /etc/nfs.conf, which I think
is a good thing...
