Delta ADS/xDS support. Added NewGrpcMuxImpl, a GrpcMux implementation that supports delta (and is intended to soon take over for state-of-the-world). DeltaSubscriptionImpl (which can soon be renamed to/replace GrpcSubscriptionImpl) now uses that new class. NewGrpcMuxImpl is the first user of the recently added WatchMap.
Risk Level: medium (huge new thing that people aren't using yet)
Testing: added delta param variant to ads_integration_test
Docs Changes: added source/common/config/README.md and accompanying diagram, added to root/configuration/overview.rst and root/intro/arch_overview/operations/dynamic_configuration.rst.
Release Notes: added support for delta xDS (including ADS) delivery
Fixes#4991

In order to better support clients such as gRPC-LB that want to access
only a single listener/cluster, provide the scope in the xDS
specification to specify explicit resource hints.
