Michael Schurter 528c426c53 Port client portion of #4392 to new taskrunner
PR #4392 was merged to master *after* allocrunnerv2 was branched, so the
client-specific portions must be ported from master to arv2.

Michael Schurter f12501d4c3 tr: implement dispatch payload hook

Michael Schurter e42154fc46 implement stopping, destroying, and disk migration
* Stopping an alloc is implemented via Updates but update hooks are
  *not* run.
* Destroying an alloc is a best effort cleanup.
* AllocRunner destroy hooks implemented.
* Disk migration and blocking on a previous allocation exiting moved to
  its own package to avoid cycles. Now only depends on alloc broadcaster
  instead of also using a waitch.
* AllocBroadcaster now only drops stale allocations and always keeps the
  latest version.
* Made AllocDir safe for concurrent use

Lots of internal contexts that are currently unused. Unsure if they
should be used or removed.

Michael Schurter 820af27171 wrap boltdb in a write deduplicator
Saves a tiny bit of cpu and some IO. Sadly doesn't prevent all IO on
duplicate writes as the transactions are still created and committed.

Deregistration works but difficult to test due to terminal updates not
being fully implemented in the new client/ar/tr.

Michael Schurter 6def5bc4f9 client: set host name when migrating over tls
Not setting the host name led the Go HTTP client to expect a certificate
with a DNS-resolvable name. Since Nomad uses `${role}.${region}.nomad`
names ephemeral dir migrations were broken when TLS was enabled.

Added an e2e test to ensure this doesn't break again as it's very
difficult to test and the TLS configuration is very easy to get wrong.
