We can drastically improve boot times on some machines, or BM or VM
shapes, if we send DHCP requests in parallel on all interfaces
Add ip=single-dhcp as a kernel boot parameter, to send DHCP requests in
parallel on all interfaces. Thus, DHCP on each interface is overlapped
thereby reducing boot times for multiple interface machines.
This can help reduce the boot time by 1 minute per interface.
In addition, we may also save another 40 secs delay per interface, if
the link on which we try to send DHCP is in DOWN state. This can be
reduced by giving the following kernel command line parameter while
booting - rd.net.timeout.carrier=<timeout>.
Added manpage for ip=single-dhcp with the caveat that it does not
apply to Network Manager or SUSE wicked.

During raid assembly mdadm will call mdadm-grow-continue.service if
reshape is in progress.
If service doesn't exist then it is done via fork and systemd will kill
it unconditionally after processing all events.
Add proper service to allow systemd to manage reshape correctly.

A recent change in Linux kernel v5.10 split the MDIO drivers from the PHY
subdirectory into a new MDIO subdirectory [0]. This caused MDIO drivers
to not be included in the initramfs.
Also include the modules of this new subdirectory to prevent this issue.

Otherwise e.g. the xts(aes) implementation provided by the vmx_crypto
module (which does usually get included on ppc64le) fails to initialize
when xts is built as a module (CONFIG_CRYPTO_XTS=m), because it can't
instantiate the fallback generic xts(aes) implementation (needs the
generic xts module).

On EL8.3 the NetworkManager keep restarting even if it exits successfully while waiting for Clevis to unlock. This patch ensures NetworkManager runs only once in initrd.
It is only installed on RHEL 8+, but as noted in the first commit
that tried to do this - 0bb9a683 - we already have branches for
all RHEL releases, so there's no point keeping such a conditional
on the master branch. After 0bb9a683, 51-dracut-rescue-postinst.sh
was re-added because Fedora 30 needed it, with a FIXME saying to
remove it after F30 was released. But instead of that happening, it
got changed to a conditional to install it on Fedora <= 30 or RHEL
<= 8 in 9e68789d and the FIXME was removed, then in 9eb1d1ed that
conditional was simplified to only refer to RHEL, so we wound up
with this situation.
Note the last two commits were never ported to the RHEL-8 branch,
so it's broken, I will send a separate PR for that.

The underlying issues this was trying to solve is to get a cheap
workaround for the fact that (open)SUSE with atomic support moved
/etc stock files to /usr/etc in order to improve compatibility. But
now that even nsswitch.conf moved, this is no longer enough. And it
might be more trouble to support once it's in an official release.
So let's rather drop it now.
This reverts commit e0524af2bf.
