sync_command and async_command in ironic_python_agent/extensions/base.py
are implemented so that they change decorated method signature,
which is really bad practice. Example:
@sync_command
def orig_method(self, **kw):
...
sync_command decorator returns lambda which has one additional
argument 'command_name'
def sync_command(func):
def decorated(self, command_name, **kw):
...
func(self, **kw)
...
return decorated
Additional parameter 'command_name' is moved from decorated function to
decorator signature in both decorators. Every call of decorated functions
is fixed, BaseAgentExtension.execute is updated to not send this extra
argument. BaseAgentExtension.__init__ automatically generates command_map
from decorated methods.
