Part2 - Customize Horizon to work with Swift standalone component
Implementation of Swift Access Url Generation in Horizon:
   Openstack Horizon doesn't provide feature to generate temporary access url for swift object. This has to be done manually via command line. With this fix, swift object access url generation can be done as part of horizon itself with input parameters - (Url Access time duration, Temp-Auth-Url-Key). Temp-Auth-Url-Key is specific to tenant and as of now this has to configured manually in the server.
