Closes: #600

Description

  • config validation upon startup for any command
  • added new CLI hermes config validate which yield a small diagnostic in case a syntactic error is found in the config file

Validation handled:

  • log_level field
  • error signalled if no chain is specified for command start
  • duplicate chain id specified
  • prevent unknown fields in the configuration

For contributor use:

  • Updated the Unreleased section of CHANGELOG.md with the issue.
  • If applicable: Unit tests written, added test to CI.
  • Linked to Github issue with discussion and accepted design OR link to spec that describes this work.
  • Updated relevant documentation (docs/) and code comments.
  • Re-reviewed Files changed in the Github PR explorer.

Should we check also that all options included in the config file are supported by the current version? And issue at least a warning? Right now they are ignored.
