Yong Tang c06179cb55 Fix issue caused by duplicate docker plugin create with same names ...

This fix tries to fix the issue raised in 28684:
1. Duplicate plugin create with the same name will override the old plugin reference
2. In case an error happens in the middle of the plugin creation, plugin directories
   in `/var/lib/docker/plugins` are not cleaned up.

This fix update the plugin store so that `Add()` will return an error if a plugin
with the same name already exist.

This fix also will clean up the directory in `/var/lib/docker/plugins` in case
an error happens in the middle of the plugin creation.

This fix fixes 28684.
