Compile Translation Files into AST Format

Overview:
Steps to Implement (See ui-plugin-find-user PR for example):

• Add @formatjs/cli as a dev-dep

  yarn add -D @formatjs/cli

• Add the following command to package.json with (replacing <ui-module-name> with your module name):

  "formatjs-compile": "formatjs compile-folder --ast --format simple ./translations/<ui-module-name> ./translations/<ui-module-name>/compiled"
  

• Run the command 

  yarn formatjs-compile

  If there are any errors, contact peter to let him know of the error and he will work with Lokalise to get the files corrected. After Lokalise corrects files, update your branch from master.

• Modify Jenkinsfile to run formatjs-compile under runScripts section:

  runScripts = [
     ['formatjs-compile': ''],
    ]
