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.

Also the v3 catalog is larger than the v2 catalog which would explain
why this bug is being hit just now.

This change adds the configuration option max_header_line to each of the
API confurations which has a default of 16384.
