Commit Message

Add support for jar'ing compile outputs in the isolated strategy. This change makes the isolated compile strategy viable out-of-the-box for use with large dependency graphs. Without it, `test.junit` and `run.jvm` performance slows down significantly due to the large number of loose classfile directories.

- Split CompileContext out into its own file and add a specialized implementation for the isolated strategy.
- Add support for replacing classpath entries.
- Added a `finalize_execute` method to GroupMember to play a role symmetrical to `prepare_execute`, which runs only if a member has relevant targets.

This helps Twitter replace a nasty hack whereby the compile_classpath was repeatedly re-jar'd by a task that (without assuming too much about the internals of jvm_compile) attempted to consolidate all directories on the classpath into jars.
