Add a parameter to take advantage of the new(ish) eventlet socket timeout
behaviour. Allows closing idle client connections after a period of
time, eg:
$ time nc localhost 9292
real 1m0.063s
Setting 'client_socket_timeout = 0' means do not timeout.
NOTE(mriedem): This patch is not 1:1 cherry-pick, I have changed the
default value of client_socket_timeout to 0, as per the policy for
changes to stable branches:
