Enable server side search and filter out retired forms when uploading mUzima form templates

mUzima Core module allows users to search for forms for which they need to upload form templates. However, the search currently works well if the number of forms available on the server does not exceed the maximum number of search results that can be retrieved via REST Webservices as set in OpenMRS settings. The reason is that the module downloads the first items in the forms list capped at the set maximum number of search results and then enables the search to happen locally based on the downloaded list.  The effect is that users cannot upload forms for form items not included in the downloaded form list. There is a need to enable server-side searching of forms while uploading as well as filtering out the retired forms from the list displayed to the user.
