Integrating WSP's Configs from their MTC work

[dhensle]

Config changes include:

• CDAP configs
• Replacing Joint tour frequency model and joint tour composition model with one joint_tour_frequency_and_composition model
• New Joint Tour Participation configs
• Non-mandatory tour frequency configs
• Parking location choice configs

Configs are running in single process and multi-process mode using the BayDAG branch (following this accompanying commit to get the configs to run).

Please view the README_configs.md file for outstanding issues or things that should be reviewed with these config changes.
