Test suite: Automate testing of 'algo test' FSM

Goal: Ability to fully verify the 'algo test' FSM on any Serenity with a single command.

Should use a standard test framework, like pytest, and implement as a test case that does the following:

• Runs the algo test setup transition once, and then runs the 'playback' transition a few times (with a different input data file each time).
• Checks the monitoring status of the device after running each transition
• Checks that only the expected set of monitorable objects are enabled after each transition, i.e. TTC interface; all other components should be disabled.
• Check I/O data after each capture transition:
  • Compare captured RX buffers with injected data
  • Compare captured TX buffers with injected data - should be offset by 7 clock cycles.

Command line flags:

• --algo-test-config: Path to config file containing values of all parameters for algo test FSM, except for the firmware package and input file
• --board: Hostname (and port) of board
• --processor: IDs of processors to use (e.g. x0, x1)
• --tolerate-monitoring-warnings: Flag warnings in monitoring as pytest warnings (without this flag, assert that monitoring status is 'good')
• --tolerate-command-warnings: Flag warnings in transitions as pytest warnings (without this flag, assert that transition end state is just 'done')
• --fw-package: Path to firmware package

Parameters for test case function:

• settings_pool: SettingsPool object created from --algo-test-config config file, with --fw-package used in replacements)
• processor: Processor object (specified by combination of --board and --processors)
• tolerate_monitoring_warnings: Corresponding to --tolerate-monitoring-warnings
• tolerate_command_warnings: Corresponding to --tolerate-command-warnings

Note: Where-ever possible, should try to make as much of this this test code as possible board-/plugin-independent. That board-/plugin-independent test code will then be migrated to the Python library repo soon.
