Execute script event handler triggers

[hlayisanimazuze]

Expose functions that make possible for us to handle success and failure from the execute script function. This could be useful in cases where would like to add additional conditions to the events such as rendering a dialog based on if a table has data,
e.g.```

if (globalState.dataTableContext.tableData.length) {
  handleSuccess()
} else {
 handleFail()
}

 or if you want to handle success after certain amount of time has elapsed e.g. if you have a `setTimeOut` function

Example: https://function-adminportal-test.shesha.dev/dynamic/Boxfusion.SheshaFunctionalTests.Common/Books-Table
1. First step you want to execute a script and when the script is done executing
2. Handle success and navigate to the details view of the record
