feat: plugins reuse excludes CLI arg

[bigpick]

Info

Addresses #132.

Allows the ability to pass a CLI flag (--plugins-reuse-excludes) that forces the plugins to not run with a default config.

Once passed in, sets plugins_reuse_excludes to true in the .secrets.baseline, which takes precedence/persists even if the CLI argument is not passed. In order to remove the setting, deleting + regeneration of the baseline without the flag is required.

Testing

setup:

mkdir issue132 && echo 'secret: mysecret' > issue132/test.txt

1. Default scan, picks up secret:

PYTHONPATH=`pwd` python detect_secrets/main.py scan --update .secrets.baseline --all-files issue132

PYTHONPATH=`pwd` python detect_secrets/main.py audit .secrets.baseline

# shows (1) Secret Type: Secret Keyword

rm .secrets.baseline

2. Scan with flag and no baseline, picks up secret:

PYTHONPATH=`pwd` python detect_secrets/main.py scan --update .secrets.baseline --all-files issue132  --plugins-reuse-excludes

PYTHONPATH=`pwd` python detect_secrets/main.py audit .secrets.baseline

# shows (1) Secret Type: Secret Keyword

rm .secrets.baseline

3. Scan with ignore, doesn't pick up secret:

PYTHONPATH=`pwd` python detect_secrets/main.py scan --update .secrets.baseline --exclude-lines "secret" --all-files issue132

PYTHONPATH=`pwd` python detect_secrets/main.py audit .secrets.baseline
# Nothing to audit! 

rm .secrets.baseline

4. Scan with ignore + flag, followed up by scan without flag, still doesn't pick up secret:

PYTHONPATH=`pwd` python detect_secrets/main.py scan --update .secrets.baseline --exclude-lines "secret" --plugins-reuse-excludes --all-files issue132

PYTHONPATH=`pwd` python detect_secrets/main.py audit .secrets.baseline
Nothing to audit!

PYTHONPATH=`pwd` python detect_secrets/main.py scan --update .secrets.baseline --all-files issue132

PYTHONPATH=`pwd` python detect_secrets/main.py audit .secrets.baseline
Nothing to audit!

jq '.plugins_reuse_excludes' .secrets.baseline
true
