[CLOB-930] Add ctx.Done() support to shutdown, make start-up wait time configurable, and add support for domain sockets for gRPC server and gRPC web server.

[lcwik]

The purpose of these changes is to be able to launch the Cosmos app from the command entry point instead of directly via dydx.NewApp in the e2e test framework.

ctx.Done() support and was added in 0.50 with cosmos#15041

server start up time was removed in 0.50 with cosmos#15041

So a lot of this change will be removed with the Cosmos 0.50 upgrade.

Description

Closes: #XXXX
