Stop hardcoding root user

Some parts of the code still use a hardcoded user name: root. This patch
replaces all with a constant specified at build time. The end goal is to
make it possible to run a Ganeti cluster without any special privileges
(of course this will prevent some functionality from working)....

DeprecationWarning fixes for pylint

In version 0.21, pylint unified all the disable-* (and enable-*)
directives to disable (resp. enable). This leads to a lot of
DeprecationWarning being emitted even if one uses the recommended
version of pylint (0.21.1, as stated in devnotes.rst)....

Add gnt-instance start --pause

Creates the instance, but pauses execution before booting. This combined
with 'gnt-instance console' unpausing instances means that the entire
boot process can be viewed and monitored.

hv_chroot: move unmount to CleanupInstance()

This allows cleanup to be done properly if the "instance" wasn't running

Extend the hypervisor API with name-only shutdown

Currently the ShutdownInstance method of the hypervisors takes a full
instance object. However, when doing instance shutdowns from the node
only, we don't have a full object, just the name.

To handle this use case, we add a new ‘name’ argument to the method,...

Fix unused imports or add silences where needed

In some cases pylint doesn't parse the import correctly, so we add
