Adding third party modules in xl-release

#1

Here is a way to add modules in future

Follow these steps:

Step 1: shut down xl-release/service
Step 2: unzip Lib file and place it in the `ext` folder like `xlr_home/ext/request`. Lib file can be downloaded either from GUI or PIP. 
Step 3: Add `features.script.sandbox.enabled =false` in `xl-release.conf `as attached. This will un-restrict xl-release sandbox for execute those third part libs.
Step 4: start xl-release and run script.

xl-release.conf will look like

xl {
    # The connection details for the target SQL database where
    # releases will be migrated to
    database {
        db-driver-classname="com.mysql.jdbc.Driver"
        db-password="{b64}zrG70vGHgGO34o81+Y/ExA=="
        db-url="jdbc:mysql://localhost:3306/xlr805?useSSL=false&nullNamePatternMatchesAll=true"
        db-username=gsajwan
        max-pool-size = 20
        max-life-time=8 minutes

    }
    reporting {
        # The connection details for the target archived SQL database
        # where releases will be migrated to
        db-driver-classname="com.mysql.jdbc.Driver"
        db-password="{b64}zrG70vGHgGO34o81+Y/ExA=="
        db-url="jdbc:mysql://localhost:3306/xlr805archive?useSSL=false&nullNamePatternMatchesAll=true"
        db-username=gsajwan
        max-pool-size = 20
        max-life-time=8 minutes
    }
   features.script.sandbox.enabled =false
}
