harep: create repair jobs

Implement 'doRepair' to create a repair job from a list of opcodes if
the instance's policy allows it (otherwise set an ENOPERM result label),
and the instance was previously healthy (i.e. not in ArFailed or
ArPendingRepair).

harep: pure function to detect brokeness with instances

Add a 'detectBroken' function that determines whether an instance is in an
unhealthy state, and what's needed to repair it. The repair is specified as
an AutoRepairType constant, and a list of opcodes. The opcodes will only be...

harep: check for completed jobs at the start of the program

As a first step before detecting any brokeness with instances, see if any
of our previous repairs have completed, and move instances to ArFailed or
ArHealthy accordingly. Do nothing if there are still running jobs for the...

harep: initial parsing of tags

Parse auto-repair tags to set each instance in one of ArHealthy, ArFailed,
or ArPendingRepair. The implementation tries to be well behaved when old
tags have been left behind, which future patches will still try not to do....

Loader.hs: ignore expired ArSuspended policies

At the moment, because 'mergeData' is pure, it may set instance auto-repair
policies that are of the form `ArSuspended $ Until timestamp_in_the_past`.
If later on the auto-repair tool notices this, it has lost access to what...

Fix a bad data type in Hcheck.hs

While trying to understand why some code was not being tested, I
realised that we have a bad data type in Hcheck.hs.

We have "data Level = GroupLvl | ClusterLvl", but then we need to pass
the group name/index as well, so we have functions that look like the...

Move src/Ganeti/HTools/Program.hs to Program/Main.hs

This removes one more tab conflict; this is the last module in our
code where we have both x.hs and x/.

Furthermore, we collapse all actual code into the new Main.hs module,
leaving the htools.hs basically empty (will allow better testing in...

Rename htools/ to src/

Per offline discussions, this is the first patch of the
renames. Tested with "make distcheck", seems to work fine.

The only change outside of the renaming is a bit of simplification in
the .gitignore rules; otherwise, simply s/htools/src/....
