Update CRC list and support 21997/7

Update CRC list and support 21997/7

- Attempt to repair IPsec LispGpe perf suite.
+ Collection name to reflect the current stable vpp.
+ Add messages found in CSIT L1 keywords.
- Uncommented (instead of deleted) untestable messages. Reasons:
 - Honeycomb.
 - Messages used by unused keywords.
 + Listed reasons. Honeycomb not mentioned if both reasons apply.
+ Delete CRC items for commands not found in keywords anymore.
+ Add CRCs from .json.api files (as teardown is hard to execute).
+ Define and restore alphabetical order.
+ Add hints to find used API commands (not entirely reliable).
+ Move used commands to "cmd = " form so hints find them.
+ Argument to run_cli_command changed from "cmd" to "cli_cmd".
+ Except also struct.error where IOError is excepted.
