add command line options for compact block threshold and gc verbose (#557)

- Feature: Added new options to zenserver for GC V2
  - `--gc-compactblock-threshold` GCV2 - how much of a compact block should be used to skip compacting the block, default is 90%
  - `--gc-verbose` GCV2 - enable more verbose output when running a GC pass
- Feature: Added new options to `zen gc` command for GC V2
  - `--compactblockthreshold` GCV2 - how much of a compact block should be used to skip compacting the block, default is 90%
  - `--verbose` GCV2 - enable more verbose output when running a GC pass
- Feature: Added new parameters for endpoint `admin/gc` (PUT)
  - `compactblockthreshold` GCV2 - how much of a compact block should be used to skip compacting the block, default is 90%
  - `verbose` GCV2 - enable more verbose output when running a GC pass
