Enable JavaScript excecution on Jenkins to be able open Squish reports

RTA Jenkins uses Squish plugin to run Squish test suites. Each time Jenkins service is booted JavaScript execution is blocked and Squish logs are not visible. Two commands need to be run in Jenkins Script console to resolve. See if those could be executed automatically on Jenkins startup:

System.clearProperty("hudson.model.DirectoryBrowserSupport.CSP");
System.setProperty("hudson.model.DirectoryBrowserSupport.CSP", "sandbox allow-same-origin allow-scripts; default-src 'self'; script-src * 'unsafe-eval'; img-src *; style-src * 'unsafe-inline'; font-src * data:");
