SERVER-31296 Update sessions, causal, and retryable in the mongo shell.

  * Removes the initialClusterTime and initialOperationTime session
    options.

  * Enables causal consistency by default when using an explicit
    session.

  * Adds a --retryWrites command line option to the mongo shell for
    enabling retryable writes in the mongo shell. The retryWrites
    options to SessionOptions is left for convenience with testing.

  * Renames setClusterTime() to advanceClusterTime(), and adds a
    corresponding advanceOperationTime() method to DriverSession.

  * Enables assigning transaction numbers for write commands where
    ordered=false.

  * Prevents the mongo shell from sending afterClusterTime or assigning
    transaction numbers when talking to a stand-alone mongod.

  * Prevents the mongo shell from assigning transaction numbers when
    using an unacknowledged (w=0) writeConcern.

  * Changes DBClientRS to re-discover the current primary of the replica
    set when it receives an error code representing "not master" in
    addition to an error message representing "not master".

  * Adds a shellPrint() pretty-printer for SessionOptions and
    DriverSession instances so they no longer print out their entire
    object definition.
