fixed incorrect "No command provided!" in ipmitool

The check for "No command provided!" in ipmitool output was failing due
to the output being a list with newline characters. This commit adjusts
the check to:
- Confirm the output list is not empty.
- Use `strip()` to compare the first list element against "No command provided!".
- DOC109 there are no type hints in the docstring arg list
- DOC110 not all args in the docstring arg list have type hints
- DOC105 type hints in these args do not match: ssh_connection
