Documentation Request Summary:

The mongo shell's API for starting a session and setting different options on it needs to be documented.

Engineering Ticket Description:

Introduce _DummyDriverSession object that forwards calls to Mongo.prototype.runCommand() with its arguments unmodified. This allows the codepaths in DB and DBCollection to go through the session object regardless of whether sessions are actually being used or not.
Add SessionOptions#shouldRetryWrites() and SessionOptions#setRetryWrites() methods.
Add retryable_writes_jscore_passthrough_WT task on the following build variants:
- Enterprise RHEL 6.2
- Enterprise RHEL 6.2 (inMemory)
- Windows 2008R2 DEBUG
- SSL OS X 10.10
- ASAN Enterprise SSL Ubuntu 16.04 DEBUG
- UBSAN Enterprise Ubuntu 16.04 DEBUG
- Enterprise RHEL 6.2 DEBUG Code Coverage
