Multi-tenant (multi NP) support

[coolbung]

Right now the protocol server can be configured with the credentials of a single NP.

We are using the Protocol Server in a SaaS service, and today we have to run separate pairs (one client mode + one network mode) of the protocol server for each NP that we host. We want to be able to run only one pair for all the NPs we host.

I'm proposing a design to handle the multi-tenancy at a DevOps level.

1. Each NP is served via a different DNS domain / subdomain
2. There should be a configuration that maps the DNS domains/subdomains to the network configuration (keys, subscriber id, webhook etc) of the NPs
3. The protocol server should be refactored such that depending on the domain/subdomain the request is coming from, the appropriate configuration should be injected for that request lifecycle

@sareenEminds Could you please check if this feature could be bumped up in our backlog? Could be useful in multiple networks coming up

@emmayank Sure. It can be picked up. It requires approval from Ravi and Faiz. This is a big change and I am not sure if they want to pick it up in the reference implementation
