superproject - More friendly user message when superproject failed.

Browse Source 
superproject is going to be default for some users. This change
doesn't fail for repo init or repo sync if source couldn't be synced
because of errors in superproject and superproject=true in the config
file. The commands will fail if --use-superproject is specified on
the command line explicitly.

The error messages are logged with trace2 event logs and will be
monitored.

+ sync - When there are errors with superproject and git_superproject
  says it is fatal failure, sync will exit only when --use-superproject
  option is specified on the command line.

+ init - command doesn't fail *if there are any superproject errors),
  but it will print a warning message and logs message via trace2 event
  logs. For fatal errors, init will exit only when --use-superproject
  option is specified on the command line.

+ All git commands log the command that is being executed so trace2
  event logs will know the manifest, remote url and the branch name.

There is no functional change other than fatal errors are honored with
--use-supeproject option with init/sync commands.

Tested the code with the following commands.

$ ./run_tests -v

Test 1 - sync'ing without errors
