Police action of tc flower now uses index to set an entry. This patch uses the police index to add or delete vcap policers, so that one policer can be shared by several rules. VCAP policers and PSFP policers share a same policer pool, so VCAP policer add or delete operations can be exported and shared with PSFP set.
