redact secrets from rage output

Summary:
# This diff
Refactors `eden rage` so that all of the output is ran through a redaction method that attempts to remove any secrets/sensitive info. Secrets/tokens are detected using a list of regexes. These are hard coded in the shared "redact" library that is used in this diff.

# Context

`eden rage` dumps out environment information and logs, which may contain secrets or sensitive information. `sl rage` protects against this by running a redaction regrex over each line of the rage and replacing any secrets with `<redacted>`. We should reuse that logic in EdenFS as well, so that we can avoid dumping secrets or senstive information to the terminal or pastry.
