Censor credentials with "****" instead of "xxxxx"
Summary: Ref T10982. There, and in other cases, it isn't obvious to users that we're censoring credentials when they see censored commands. Try using "****" instead of "xxxxx" to hopefully make it more clear.
Test Plan:
- Ran unit tests.
- Ran repository pull --trace, saw this output:
>>> [20] <exec> $ git clone --bare -- '********' '/Users/epriestley/dev/core/repo/local/55' <<< [20] <exec> 3,998,331 us
