- Closes #1206. - Closes #1185. - Closes #507. - Addresses existing log messages for #642. - Nondeterministic CI errors are resulting from very slow launch times for the first runtime helper, which causes ContainersService to be locked for longer than our 20 sec timeout. Bumping the timeout to 60 seconds addresses this case for now. - Since many log messages needed to be changed to troubleshoot the issue, updated all log messages to use structured logging, and implemented consistent entry/exit logging for all service operations. - Added logging for ContainerService lock acquisition to help with finding root cause for the slow service startup. - Plumbed the `--debug` flag on both `container system start` and `container system logs` so that the flag is actually useful. - Updated the `install-init.sh` script so that can install in a custom app root directory.
