Extract ConfigReader from Confd/Server.hs

Confd's functionality to watch the Ganeti configuration file is
extracted to the ConfigReader module. No functional changes are
introduced.

This extraction makes will enable us to split queryd from confd, as
queryd will have to use the same functionality....

Make Confd client usable for testing

Allow the Confd client to be able to connect to an arbitrary server
instead of just the real one running on a cluster.

This is meant to be used for testing.

If a data collector using the Confd client is tested with shelltest, it will...

Renames and cleanup of variable names in confd

The current names are quite confusing; this patch cleans up the
confusion by making sure we use different terms for the two threads,
etc.

No actual code changes besides the renames.

First part of confd timer changes

This patch changes the resolution of the timers: the watcher timer
goes from 60s to 17s, and the polling-mode timer goes from 2 seconds
to 250ms. The code changes a bit more due to the changes in the units
of the various constants....

Change the polling thread sleep behaviour

Currently, the polling thread sleeps at the end of its body; the
original reason was that when the thread initially starts, we want to
load the config immediately (in the old-style config load model).

However, now we explicitly load the config, so we can make this thread...

Start confd in notify mode if we can

This patch changes the default model—where confd is always started in
polling mode—to a model where if possible we enable inotify mode
before starting any of the background threads.

There are some tricky details here: if we enable inotify, we should...

Explicitly load the config at confd startup

Currently, confd main function doesn't load the config, but simply
forks the individual timer threads, which will—as a side effect-also
load the configuration as soon as they start.

However, this makes codes to the startup more complex, so let's...

Move getCurrentTime from Confd.Utils to Utils

The getCurrentTime function is of wide interest, so its moved to a more
appropriate position.
