For some reason tests work fine running manually but when run from the makefile it's not. |

In some circumstances we were not properly releasing plugin references, leading to failures in removing a plugin with no way to recover other than restarting the daemon. 1. If volume create fails (in the driver) 2. If a driver validation fails (should be rare) 3. If trying to get a plugin that does not match the passed in capability Ideally the test for 1 and 2 would just be a unit test, however the plugin interfaces are too complicated as `plugingetter` relies on github.com/pkg/plugin/Client (a concrete type), which will require spinning up services from within the unit test... it just wouldn't be a unit test at this point. I attempted to refactor this a bit, but since both libnetwork and swarmkit are reliant on `plugingetter` as well, this would not work. This really requires a re-write of the lower-level plugin management to decouple these pieces. Signed-off-by: Brian Goff <[email protected]>
