"Items per page" value setting is applicable only to those pages that have API supported pagination. For example, if "Items per page" value is set to say "3" and if we go to Admin > Identity Panel > Users page, more than "3" items will be displayed if present. This is confusing to users. So as part of this commit, the help text is modified to reflect this limitation. Change-Id: Ibbd4771829f0c312134eb275c797780be2b78410 Closes-Bug: 1431364
