harep: finish execution with a summary of instance states

The harep tool prints messages for every action that it performs (or that
it doesn't perform). In case nothing is to be done at all, always print
some statistics of the current state of the cluster....

harep: do not wait for repair job completion to set tags

Because of instance locks, after submitting a repair job we weren't able to
set the "pending" tag until at least the first opcode of the job finished.
Introduce a small delay in the repair job so as to allow the subsequent...

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...
