Ian Campbell e5e578abc7 Allow plugins to make use of the cobra `PersistentPreRun` hooks. 
Previously a plugin which used these hooks would overwrite the top-level plugin
command's use of this hook, resulting in the dockerCli object not being fully
initialised.

Provide a function which plugins can use to chain to the required behaviour.
This required some fairly ugly arrangements to preserve state (which was
previously in-scope in `newPluginCOmmand`) to be used by the new function.

Ian Campbell 5db336798c Add some simple e2e tests for executing CLI plugins 
To help with this add a bad plugin which produces invalid metadata and arrange
for it to be built in the e2e container.
