Document dispatcher methods

[itdependsnetworks]

Currently when the dispatched fails, the operator is provided with an error based on f"Unable to find the driver for {method} for platform: {task.host.platform}"). It would be good to add a link into that error message to point to a website of what was supported from a platform and method perspective, similar to the napalm getters.

yes, something like f"Unable to find the driver for {method} for platform: {task.host.platform}, and expect {netutils.config.compliance.join(', ')}")
