tslint analyzer ignores exclude rule

Summary

The TSLint Analyzer as part of SAST functionality appears to ignore exclusion rules. Similar exclusion rules for ESLint are applied correctly. For a NodeS project with a node_modules directory the TSLint analyzer attempts to process all files beneath regardless of exclude directives attempted.

Steps to reproduce

Added the following to tslint.json at project root with various globs defined (node_modules/**,**/node_modules/**, /node_modules/ etc)

  "linterOptions": {
    "exclude": [
      "node_modules"
    ]
  }

But according to documentation that is only relevant for CLI usage, so next attempt was the following within tsconfig.json

  "exclude": [
    "node_modules"
  ]

With no change in processing.

What is the current bug behavior?

Excluded path is processed. In the node_modules case the default was expected to be an ignore.

What is the expected correct behavior?

No files within the excluded path are processed.
