/**
 * Wrapper for exec.exec which checks for specific return code and/or regex matches in console output.
 * Output will be streamed to the live console as well as captured for subsequent processing.
 * Returns promise with return code
 *
 * @param     commandLine        command to execute (can include additional args). Must be correctly escaped.
 * @param     matchers           defines specific codes and/or regexes that should lead to return of a custom error
 * @param     args               optional arguments for tool. Escaping is handled by the lib.
 * @param     options            optional exec options.  See ExecOptions
 * @returns   Promise<number>    exit code
