Sergey Kizunov cb326f06da Fixed memory leak in AsyncTCPReqChannel
`cls.instance_map` was growing unbounded. This was because
`io_loop.close()` was invoked before `stream.close()`. The stategy used
to fix this issue was discussed in pull request #28530 and can be
summarized as follows:

The `close()` method on the async object will be called if it exists.
This will be called before the `io_loop.close()` to give the async object
the opportunity to close its stream. The del of the async object will
continue to happen after io_loop.close(). This is to maintain the fix
from pull request #27343.

Per file change details:
salt/utils/async.py:
- Implemented the close logic described above.

salt/transport/ipc.py:
- Ensured that `close()` may be invoked more than once safely.
- In IPCServer, `self.stream` was never actually used. Removed
references to it to avoid confusion.

salt/transport/zeromq.py:
- Ensured that `close()` may be invoked more than once safely.

salt/transport/tcp.py:
- Ensured that `close()` may be invoked more than once safely.
- Changed `destroy()` methods to `close()` methods since they involved
a stream that should be closed before `io_loop.close()`.
- In SaltMessageClient, added more checks for `self._closing`. This
makes exit cleaner by not attempting to reconnect while closing.
- Removed the code associate with pull request #28113. This code is
no longer needed now that the stream is closed before the io_loop.
