Ensure plugins default search path obeys `--config`

A static global initialiser happens before the arguments are parsed, so we need
to calculate the path later.

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.
