RunCmd: Expose "postfork" callback

The “_postfork_fn” parameter was only used for tests until now. To
implement a good locking scheme, remote commands must also make use of
this callback to release a lock when the command was successfully
started (but did not yet finish)....

RunCmd: Support standard input file descriptor

This patch changes “utils.RunCmd” to accept a file-like object or a
numeric file descriptor which will be used as the command's standard
input. One use-case will be to pass all necessary data to
“prepare-node-join”....

Log all external commands execution

This logs all external commands in normal (non-debug) mode. This will
leak the DRBD secrets, but in any case we do log failed commands, so
it's not a significant change.

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)....

Reopen daemon's stdio on SIGHUP

Before this patch daemons would continue to refer to an old logfile for
their standard I/O if they had been asked to reopen the log (SIGHUP).

Don't leak file descriptors when setting up daemon output

When a daemon's output is configured using “utils.SetupDaemonFDs”, the
function must use dup2(2). Unfortunately the code didn't close the
original file descriptors, leaking them in the process.

Add ability to retain specified fds open in RunCmd

Passing tap devices to KVM as file descriptors requires that the respective
file decriptors remain open during utils.RunCmd execution. To this direction,
we add a “noclose_fds” keyword argument to utils.RunCmd, accepting a list of...
