Implement AutomatedMaster

[mssalvatore]

Implement a concrete AutomatedMaster in support of the agent refactor effort ^{1, 2}. Use the pseudocode from the design as a starting point.

Note: As #1595 will already be complete when this issue gets resolved, don't forget to revisit the Windows signal handler for CTRL_CLOSE_EVENT signals.
