rest-hapi plugins support/docs

[SukantGujar]

Is your feature request related to a problem? Please describe.

Loopback provides a rich plugin framework, resulting in cherry picked enhancements to the core offering. If rest-hapi has a similar mechanism, the docs should be written around it. If its not there yet, are there any plans for it?

@SukantGujar Currently all rest-hapi features are included as part of the core library, and can either be enabled or disabled through the config settings.

However I would prefer for it to be structured as you describe, as it is much more flexible/modular. Hopefully in a future release this can be accomplished.
