Allow passing extra GRPC services to AdminServer

[eranrund]

Motivation

A bunch of our applications already include this internal, privileged GRPC server, and it could be convenient to use it for extra app-specific functionality.

Specifically, I want to add some admin commands to the DEQS liquidity bot, and it already has this GRPC server, so it seemed like the right place for it, but at the moment there's no way to add extra GRPC services so I either copy-paste AdminServer, or we extend it to allow passing of extra GRPC services.

If you want this for deqs repo, are you going to bump deqs repo to point at master?
I thought we have it on 4.1 for compatibility

Oops yeah this should be against release/v4.1, thanks

[cbeck88]

seems fine to me

This should be pointed at master: we haven't done any testing on this at all, it wasn't brought up in any meeting, and we're releasing in < 6 hours.

5.0 is (tentatively) scheduled for release on Monday, there's literally zero point to put this into the stable branch at this late a stage.

It's too late to add new features to 4.1.

[cbeck88]

Maybe we can do a 4.1+dev branch for the deqs so that we arent building against master for prod?

[eranrund]

I don't remember whats getting into 5.0 but maybe we can just move the DEQS to point at 5?

[jcape]

The current plan is for master to become release/v5.0 next week, and it will include dependency updates, more work on hardware wallet support, updated dalek and friends, a rust update, and the fog view and ledger routers.

release/v4.1 is being released today. We have an hour set aside every week to discuss what goes into what releases and what the timelines are, and we've already pushed release/v4.1 back several times.

Im not asking to push back release/v4.1 -- lets chat offline

It also may be fine to bump deqs to 5, im not sure. But id like to demo it soon against testnet and i expect there may be breaking changes in 5
