Handle unknown arguments for commands

[evik42]

Handle unexpected / unknown arguments sent in a API command.

Currently if a command is sent to the ya-runtime-vm it will silently ignore any flags, parameters passed in the command that it does not recognizes.
This is a problem when the parameter/flag changes the behavior of the command (for example the start-entrypoint flag for Start command).
Unknown, unexpected flags/parameters in the command should cause an error as the runtime does not know how to fulfill the request.
