Remove the JVM global compile strategy, switch default java compiler …

…to zinc

On the assumption that Foursquare's switch to the isolated compile strategy will stick, this patch deletes the global strategy.

- Inline all of the isolated strategy into jvm_compile
- Merge pants.ini files
- Delete the global strategy and strategy interface
- Make `zinc` the default for java compiles since jmake does not support partitioned analysis
- Update `migrate_config` to indicate the global-related options will be ignored

Testing Done:
pantsbuild#2227
