Regression in .sastscanrc behavior for scan_type

[erichs]

Versions 1.15.8 and previous support setting scan_type in a local .sastscanrc and Versions 2.0.0+ do not.

Given a local .sastscanrc (pulled from test/data/.sastscanrc):

{
    "build_break_rules": {
        "default": { "max_critical": 0, "max_high": 0, "max_medium": 0 }
    },
    "scan_tools_args_map": {
        "go": ["echo", "hello", "world"]
    },
    "scan_type": "credscan,java"
}

The following commands demonstrate the regression:

❯ docker run --rm -e SCAN_DEBUG_MODE=debug -e "WORKSPACE=${PWD}" -v ${PWD}:/app shiftleft/scan:v1.15.8 scan --mode ci --src /app

Amazing! Ty, sir.
