• deprecate legacy tx endpoint
  According to this document, the POST endpoints of the New gGPC-gateway REST are N/A and guided directly to use Protobuf, so we will also deprecate the POST endpoints of the liquidity module.

• added description and example

• liquidity_pools_response → pools

• liquidity_pool_meta_data → liquidity_pool_metadata

• deposit_msgs[i].Msg → deposits[i].msg

• succeed to succeeded

• to_delete to to_be_deleted

• swap_msgs → swaps
