Match some default value to keep the same code when switching from sync to async

This complies with the original behavior before refactoring.

Optimize processing with some standard data structures.
Stop adding reverse references to HasTypeDefinitions.

instead of Node.to_string 
_node_to_string correctly maps namespaces idxs

In non strict_mode most errors are just logged an the import continues.

    [HaClient] Allow init from executor

    With py3.10, high level asyncio API can't specify the event_loop
    argument anymore.

    Consequently When using thread dedicated to run the event_.loop, we now need to
    instantiate object like asyncio.Lock within the thread. However, the
    event loop can't be running before creating these objects as
    `loop.run_for_ever()` must be the background running thread process.
    Therefore we can't have "get_running_loop()" calls in object
    constructors (like HaClient)
    when used with executors.

    Before
    ```

        ...:     loop = asyncio.new_event_loop()

    In [16]: class T:
        ...:     def __init__(self, loop):

        ...:         self.l = asyncio.Lock()
        ...:         print("Lock created")

    * Update xmlparser.py

    with this we can set the value to newly created datatypes

    * Update ua_utils.py

    This is conform to the I40AAS nodeset enumerations, e.g. given enumeration as "AccessPermissionRule_0" specifying the type and the integer

    [Safe Client disconnect]
    Follow-up of #711
    Make sure calling disconnect is safe when connection isn't established
    or half-established (i.e: protocol/transport exist but session is not
    ready).

    Test1
    Call to disconnect is safe when there's no existing connection
    ```
    > python -m IPython
    Python 3.10.0 (default, Oct 13 2021, 06:45:00) [Clang 13.0.0 (clang-1300.0.29.3)]

    In [1]: import sys; sys.path.insert(0, "~/Documents/github/opcua-asyncio"); import asyncua; c = asyncua.Client(url="opc.tcp://localhost:4840",timeout=10
       ...: );

    In [2]: await c.disconnect()
    close_session but connection wasn't established
    close_secure_channel was called but connection is closed

    In [3]:
    ```
    Test2

    Calling to disconnect is safe when there's no session established.
    To simulate this, I add delay to the server internal_session on session
    creation. I check that the client connects and disconnect from the
    server logs. Finally, the client doesn't raise any error.
    Ad delay to the internal server
    ```

    [HaClient] Fix test race condition

    According to the logs of the recent test failure, there's a small window when we test the connection is established where we have a socket connected but don't have the session created yet, and this is throwing exception when trying to disconnect because the renew loop is not yet created.

    This is caused by the HaManager (in charge of connecting/reconnecting the clients) running in its own task, thus we're not in the usual await connect(); await disconnect() scenario.
    This can also arguably be fixed at the client level by checking if
    the renew loop exist on disconnect.

    [PyPi] Missing files

    The HaClient is missing from the PyPi package:

    The build rules only look for the packages via
    (`find_packages`) in setup.py, making the ha client sub-directory a
    package fixes it:
    ```

    [Sec_Policy] Handle server certificate renewal gracefully

    When a client reconnects, it can require to clear its security_policy
    settings to deal with situations where the peer_certificate has
    changed for example (regular server cert renewal).

    This PR introduces the `reset_security_policy()` client method to handle
    this use-case, and adds it to the HaClient reconnection mechanism.

    Note: We could arguably invoke this method from `set_security()` as they
    often will be called together, but according to [OPC-UA Part4 5.4.4](https://reference.opcfoundation.org/v104/Core/docs/Part4/5.4.4/),
    the GetEndpoints service may require TLS and so enforcing an empty policy would break this use-case.

    Fix crash if server does not provide DiscoveryUrls

    The OPC UA specification does not forbid that a server does not offer DiscoveryUrls. This can lead to a crash when calling the function application_to_strings().

    Check DiscoveryUrls for None or empty before iterating to avoid the crash described in #1127.

* Fixes #929 : error in Client.activate_session()

Fixes the error that a call to Client.activate_session() without arguments overwrites a user certificate previously set with Client.load_client_certificate(user_cert_file).

* Do not override already set user certificate

If you set the user certificate with Client.load_client_certificate() and then activate the session with Client.activate_session() without passing the certificate as an argument, the previously set certificate is discarded.
