A base class for implementing Netconf connections

to mark literal strings as byte string (``b"string"``) and to use
:func:`~ansible.module_utils._text.to_bytes` and

List of supported rpc's:
:get_config: Retrieves the specified configuration from the device
:edit_config: Loads the specified commands into the remote device
:get: Execute specified command on remote device
:get_capabilities: Retrieves device information and supported rpc methods
:commit: Load configuration from candidate to running
:discard_changes: Discard changes to candidate datastore
:validate: Validate the contents of the specified configuration.
:lock: Allows the client to lock the configuration system of a device.
:unlock: Release a configuration lock, previously obtained with the lock operation.
:copy_config: create or replace an entire configuration datastore with the contents of another complete

For JUNOS:
:execute_rpc: RPC to be execute on remote device
:load_configuration: Loads given configuration on device
Note: rpc support depends on the capabilites of remote device.
:returns: Returns output received from remote device as byte string
Note: the 'result' or 'error' from response should to be converted to object
of ElementTree using 'fromstring' to parse output as xml doc
'get_capabilities()' returns 'result' as a json string.
