Too short timeout

[runborg]

This is at least in 1.0, not sure if its in 0.9

When code is waiting for response from zino after sending a command it looks like the timeout some times is to short. if zino is busy it could take some seconds to get a reply.

The code failed after 10 sec while waiting.

Traceback (most recent call last):
  File "/home/runarb/src/zinolib-keepalive/zinolib-env/lib/python3.10/site-packages/zinolib/ritz.py", line 381, in _request
    data = self._sock.recv(recv_buffer)
TimeoutError: timed out

The above exception was the direct cause of the following exception:

i believe we have the same issue in 0.9 and 1.0 as i've seen Timeout errors in the client when large tings happens in the network. but cannot verify if this is the same issue or not.

This line sets the default timeout to 10sec, i think this timeout is to short because the old tcl server could potentially use over 10sec to deliver a result when it is under load
