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

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

In particular:

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,
