Implement support for CRaC

[jbedell-newrelic]

Several adjustments made:

• Close .new and .old files after weaving.
• Implement the CRaC Resource interface on the connection to the collector to close and re-open the connection.
• Implement the CRaC Resource interface on the logger to close and re-open the file.
• Added a feature flag to load our log config programmatically rather than from the config file, default is programmatic.
• This feature will only work after the supporting JDKs have released the fix for https://bugs.openjdk.org/browse/JDK-8349365

I feel funny having the supportability metric in the http client wrapper. It could as well be in the Logger, but it is a responsibility of neither.
Almost feel like we should have a CracService or util that registers itself with Crac for the callbacks, and our listeners would then register on this.
But this is just another abstraction/complexity layer just to keep up with the single responsibility principle.
So I won't hold the review because of this. But I think the other things are worth a look.
