Add support HMAC SHA1 validator

[jaximan]

Hi, really like krakend, great job!
Wondering if support exists, or open to contribution for it. Brief search, didn't show any existing module for it.

Is your feature request related to a problem? Please describe.
Would like to use krakend as proxy for Github hooks with Secrets token in header, which encoded with HMAC SHA1

Describe the solution you'd like
A router or bridge plugin, that will have access to request headers and will validate token with provided security key(from env variable). Ideally with request termination if not valid.

Describe alternatives you've considered
Custom golang module that will do the same, and available for community. Custom build of krakend with additional code, but in private repo.
