Cleanup alive monitor config loading

[WilliamRoebuck]

This is the first step of a refactor to better integrate alive supervision and launch manager. The main change in this PR is constructing alive supervision objects component by component using the new config, instead of all components at once, stage by stage. In addition, the PR:

• Removed unused config & constants
• Replaced many strings with IdentifierHashes
• Removed alive monitor config wrappers
