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....

HTools/Types.hs: minor adjustments to auto-repair types

In particular:

- make ArHealthy take an optional AutoRepairData; this allows to
    represent the situation where a repair completed successfully, and
    hence there's an associated tag we might want to know about....

Jobs.hs: start with a shorter delay in waitForJobs

Instead of waiting 15 seconds every iteration of the waiting loop, start
with 0.5 seconds and increment exponentially until a certain maximum is
reached. Keep the maximum at 15 seconds.

any of the submitted jobs doesn't succeed.
