fix: openapi tests for besu, htlc-eth-besu and htlc-eth-besu-erc20

Changes endpoints getSingleStatus and getStatus in htlc-eth-besu
and htlc-eth-besu-erc20 which now are of type post and defines
for that new request schemas.

Includes tests for all endpoints in besu, htlc-eth-besu and
htlc-eth-besu-erc20, each of them with test cases:
  - Right request
  - Request including an invalid parameter
  - Request without a required parameter

Closes hyperledger-cacti#1291

Relationed with hyperledger-cacti#847
