Adds 2 new methods to v2 plugin `Acquire` and `Release` which allow
refcounting directly at the plugin level instead of just the store.
Since a graphdriver is initialized exactly once, and is really managed
by a separate object, it didn't really seem right to call
`getter.Get()` to refcount graphdriver plugins.
On shutdown it was particularly weird where we'd either need to keep a
driver reference in daemon, or keep a reference to the pluggin getter in
the layer store, and even then still store extra details on if the
graphdriver is a plugin or not.
Instead the plugin proxy itself will handle calling the neccessary
refcounting methods directly on the plugin object.
Also adds a new interface in `plugingetter` to account for these new
functions which are not going to be implemented by v1 plugins.
Changes terms `plugingetter.CREATE` and `plugingetter.REMOVE` to
`ACQUIRE` and `RELEASE` respectively, which seems to be better
adjectives for what we're doing.

Legacy plugins expect host-relative paths (such as for Volume.Mount).
However, a containerized plugin cannot respond with a host-relative
path. Therefore, this commit modifies new volume plugins' paths in Mount
and List to prepend the container's rootfs path.
This introduces a new PropagatedMount field in the Plugin Config.
When it is set for volume plugins, RootfsPropagation is set to rshared
and the path specified by PropagatedMount is bind-mounted with rshared
prior to launching the container. This is so that the daemon code can
access the paths returned by the plugin from the host mount namespace.

Upon each container create I'm seeing these warning **every** time in the
daemon output:
```
WARN[0002] Your kernel does not support swap memory limit
WARN[0002] Your kernel does not support cgroup rt period
WARN[0002] Your kernel does not support cgroup rt runtime
```
Showing them for each container.create() fills up the logs and encourages
people to ignore the output being generated - which means its less likely
they'll see real issues when they happen. In short, I don't think we
need to show these warnings more than once, so let's only show these
warnings at daemon start-up time.

Dump stack dumps to exec root instead of daemon root.
When no path is provided to the stack dumper, such is the case with
SIGQUIT, dump to stderr.

This seems clearer to me and avoids a miniscule amount of string formatting.
I have deliberately not changed the tests here to avoid the possibility of
changing both wrongly.

Although our use of ANSI codes here is rather simple it is generally good
practice to use terminfo in order to be portable to different terminal
emulators.
Vendor github.com/Nvveen/Gotty (actually my fork with a fix, see
https://github.com/Nvveen/Gotty/pull/1) and use that to parse the terminfo
files.
Note that "\e]2K" (clear entire line) is not covered by terminfo. We can
achieve the same end by first clearing from begining of line to cursor
(el1="\e]1K") and then clearing from cursor to end of line (el="\e]k").
Test suite has been updated and forces (either directly or by setting $TERM to
something highly unlikely to exist) the use of the non-terminfo fallbacks which
retains the same output behaviour as previously. This is preferable even to
relying on a well-known and relatively static terminfo (like vt102) since even
that in principal might have different terminfo encodings.
In case terminfo is not available at all for $TERM or doesn't expose the
specific capabilities which we use then fall back to the previous manual
escapes, with the exception that we avoid "\e]2K" as discussed above.
Tested with a manual docker pull with rxvt-unicode ($TERM=rxvt-unicode), xterm
($TERM=xterm), mlterm ($TERM=mlterm) and aterm ($TERM=kterm).

feeds and spacing such that the expected and actual strings are aligned in the
same columns making comparisons easier.
