Extend availability end date of content Items on portal

[raghavs046]

This action will allow the users to extend the “Availability End Date” of Content items on portal so that they remain visible for extended period.
This will require cross scope privileges to be allowed from source scope to “Content Publishing” scope.

Example: Content Publishing is used to show campaigns and few campaigns are extended beyond period of time, this will help the extension as well as tracking.

Inputs:

1. Name = Select Content , field type = Reference , table = sn_cd_content_portal, Mandatory = true
2. Name = Availability end date , field type = Date , Mandatory = true

Output:

1. Name= Updated Message , field type = String
