Use hashicorp/go-memdb instead of truncindex
memdb already knows how to search by prefix so there is no need to keep
a separate list of container ids in the truncindex

97b16aecf9 Fix issue of filter in docker ps where health=starting returns nothing
This fix tries to address the issue raised in 35920 where the filter
of `docker ps` with  `health=starting` always returns nothing.

The issue was that in container view, the human readable string (`HealthString()` => `Health.String()`)
of health status was used. In case of starting it is `"health: starting"`.
However, the filter still uses `starting` so no match returned.

This fix fixes the issue by using `container.Health.Status()` instead so that it matches
the string (`starting`) passed by filter.

This fix fixes 35920.

1d9546fc62 container: Fix Delete on nonexistent container
Delete needs to release names related to a container even if that
container isn't present in the db. However, slightly overzealous error
checking causes the transaction to get rolled back. Ignore the error
from Delete on the container itself, since it may not be present.

1128fc1add Store container names in memdb
Currently, names are maintained by a separate system called "registrar".
This means there is no way to atomically snapshot the state of
containers and the names associated with them.

We can add this atomicity and simplify the code by storing name
associations in the memdb. This removes the need for pkg/registrar, and
makes snapshots a lot less expensive because they no longer need to copy
all the names. This change also avoids some problematic behavior from
pkg/registrar where it returns slices which may be modified later on.

Note that while this change makes the *snapshotting* atomic, it doesn't
yet do anything to make sure containers are named at the same time that
they are added to the database. We can do that by adding a transactional
interface, either as a followup, or as part of this PR.

edad52707c save deep copies of Container in the replica store
Reuse existing structures and rely on json serialization to deep copy
Container objects.

Also consolidate all "save" operations on container.CheckpointTo, which
now both saves a serialized json to disk, and replicates state to the
ACID in-memory store.
