Raise the default max header to accommodate large tokens
PKI tokens hit the default limit if there is enough services defined in the keystone catalog. So sahara should allow users to customize max header size and also increase the default value from 8192 to 16384. Change-Id: If3daff1ba18f7fcd4cf3b7d9b4152b551d8ad277 Closes-Bug: 1190149
