introduces `raise_on_parsing_error` parameter to `send_command`

[Kircheneer]

Allow exceptions from structured data parsers to bubble up to the callers of send_command and send_command_timing. This is useful for example in conjunction with nornir_netmiko, which currently can't fail tasks based on failed parsing, leading to successful tasks with garbage data.

[Kircheneer]

As discussed on Slack I have renamed the parameter and added an initial set of tests.

Please approve CI workflow whenever possible. Thanks!
