Description of problem:
Kickstart profile create via kickstart file import does not handle $(command) syntax correctly. Every time the kickstart profile is saved by clicking the "Update" button, a new backslash character is added in front of the $ symbol. This breaks the post-section if any commands use this syntax.

Version-Release number of selected component (if applicable):
Red Hat Network Satellite 530

How reproducible:
Always

Steps to Reproduce:
1.Login to WebUI
2. Manage Kickstarts
3. click 'upload new kickstart profile'
4.Fill up the values
5. In File Contents add:
export oct3=$(echo $IP | cut -f4 -d.)
6. click Create

Actual results:
Create will escape the dollar ($) sign and will prefix it with '\' :
export oct3=\$(echo $IP | cut -f4 -d.)
If you update the kickstart again by just cliking the 'Update' button or even the 'Upload File' button it will show:
export oct3=\\$(echo $IP | cut -f4 -d.)

Every POST to that page adds a extra '\'.

Expected results:
Updating an imported kickstart profile does not add extra backslashes when $(command) syntax is used in kickstart file.
