Now that we use dependency injection, this is handled by a dedicated
service (MasterWorkerService). As a side effect, stream updates aren't
necessarily fired on the ui thread, so we refresh the grid on a form
timer callback.
Namely, in DataStreamPublisher and PubSubServer. This is part of a broader
paradigm shift towards Dependency Injection and Factory Pattern.

* Use interfaces to decouple services:
- Decouple ManagedSubscriber from ISubscriberCore impl
- Decouple PubTableBroker from IPublisherCore impl
- Decouple RemoteQueryManager from IManagedSubscriber, IPubTableBroker impl
* Rename Publishers -> PublisherNodes in DataStreamPublisherConfig
* Model config profiles after dotnet appsettings
- Rename Configurations/<name>.json -> appsettings.<name>.json
- Make json fields match corresponding csharp props verbatim
* The Dependency Injection framework doesn't support JsonPropertyName
attributes. Config class props must match json fields verbatim.
* Move reusable startup code into new Bts.Extensions.Hosting proj
* Add pubsub and md-publisher services to compose.yaml
This is needed to build DataStreamSuite on Linux.
'Stopwatch' is a platform independent timer class included with the
System.Runtime library in modern dotnet. 'HighPerformanceTimer' is a BTS
class that predates Stopwatch, and is NOT platform independent as it
relies on Windows kernel32.dll QueryPerformanceCounter/Frequency fns.
All lex/yacc scanners/parsers are now generated with a proper dotnet
nuget pkg, YaccLexTools.
* Implements BooleanExpressionFilter with the new Parser.
