Job option (variable) auto-sorting as text the Allowed Values list

[Daryes]

Describe the bug
When entering a list in the "Allowed Value" text area in a new option (or variable), the list is automatically sorted when the option is saved

My Rundeck detail

• Rundeck version: 3.0.11
• install type: deb
• OS Name/version: Ubuntu 18.04

To Reproduce
Steps to reproduce the behavior:

1. Create a new job or edit an existing one
2. add a new option
3. populate the mandatory informations
4. select the Allowed Value text area, and enter : 15,30,60,90,180,360
5. save the option.
6. edit the saved option, check the Allowed Value area, the following information will be present : 15,180,30,360,60,90
   Of course, this sorted order will be kept in the job definition.

Expected behavior
expected list : 15,30,60,90,180,360
The saved value list should have been either not sorted, or numerically sorted.
