#### Description

A new parameter timeout_mode is added. This parameter defines if timeouts are enabled, and in which unit timeout values are expressed. - 0 - Timeouts are disabled. - 1 - Timeout values are in seconds (default). - 2 - Timeout values are in milliseconds.

For reference, see discussion in: https://github.com/kamailio/kamailio/pull/3611

Implementation detail:

``` default global timeout = 0 (unconfigured).

Parse connections as usual. If they have a timeout configured, use it.

In mod_init: if global timeout == 0 (unconfigured), and timeout_mode is 1 or 2: if timeout_mode == 1 -> global timeout = 4 (seconds) if timeout_mode == 2 -> global timeout = 4000 (milliseconds)

for each connection "conn" (fixup): if timeout_mode is not 1 or 2 -> conn.timeout = 0 (to reflect the fact that no timeout will be handled) else if conn.timeout is not configured -> conn.timeout = global timeout (in seconds or milliseconds, depending on timeout_mode).

When doing Curl requests (curL_request_url): if timeout_mode == 1: set CURLOPT_TIMEOUT if timeout_mode == 2: set CURLOPT_TIMEOUT_MS ```
