Adapt CORS filter to multiple domains (organizations)

[otsakir]

CorsFilter should be able to work with multiple domain names and establish a convention that will connect restcomm domain and rvd domain.

For example given that we have two organizations A and B with domain names A.restcomm.com and B.restcomm.com, RVD requests with the following Origins should get the CORS headers attached:

rvd.A.restcomm.com and rvd.B.restcomm.com

The filter should be able to consider existing organizations names and the exact convention used.
