Ability to use singular custom endpoints

[ahinkle]

PR allows for singular custom endpoints.

Currently, you can use custom endpoints:

rest/all/V1/foo/bar

$magento->api('foo')->get('bar');

But we are unable to use custom singular API endpoints:
rest/all/V1/foo

$magento->api('foo')->get();

ping @VincentBean, fyi - small changes on singular custom routes.

Nice! Does this work for post requests too?

$magento->api('foo')->post($data);

Or do we have to do it like so:

$magento->api('foo')->post('', $data);

Thanks for the ping :)

Yeah, correct -- unfortunately, $magento->api('foo')->post('', $data); but open to PRs. 👍
