Add a resmoke bisect sub-command that wraps around git bisect. It'll compile the Server and run resmoke with a repeat of 100 to capture flakiness tests under git-bisect.

We need users to be able to configure the compile and resmoke commands based on git commits. Something like the following:

- startGitVersion: xyz
   setupCommand: source ./script-to-setup-venv-and-install-pip-dependencies
   compileCommand: scons ijk
   resmokeCommand: resmoke.py abc
- startGitVersion: xyz
   compileCommand: scons ijk
   resmokeCommand: resmoke.py abc

• We will need to make a template of the config YAML with global changes to resmoke and compile steps, e.g. resmoke.py -> resmoke.py run.
• The script will need to be tested on Ubuntu 1804 (which is the majority of virtual workstations). We'll make a best-effort to ensure it works cross platform by avoid using platform-specific code where possible. (We do not intend for this to be run outside of virtual workstations, as it would take a very long time due to the lack of icecream cluster access.)
