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....

CLI.hs: fix double spaces in option help strings

Some help strings with continuation backslashes ('\') were providing a
space both before and after the backslash, resulting in double spaces in
help output. Provide it only after the backslash, which fixes the issue and...

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...

Loader.hs: set instance auto-repair policy in mergeData

'getArPolicy' and 'setArPolicy' follow the precedence rules introduced in
b1eb71c: within an object, the most restrictive tag wins; across object,
the nearest tag wins.
