Sentry-python does not set connection timeouts

[aivarsk]

How do you use Sentry?

Sentry Saas (sentry.io)

Version

2.25.1

Steps to Reproduce

When sentry-python tries to report errors during network failures, it may hang up forever while trying to connect.

Expected Result

Inside transport.py both _get_pool_options it should set timeouts to something reasonable like:

        options["timeout"] = urllib3.util.Timeout(connect=5, read=5)

That will allow process to terminate during network failures.

Actual Result

When the PoolManager is created, it gets the default timeout values (https://urllib3.readthedocs.io/en/stable/reference/urllib3.util.html#urllib3.util.Timeout)

Timeout(connect=<_TYPE_DEFAULT.token: -1>, read=<_TYPE_DEFAULT.token: -1>, total=None)

This leads to connect call being made in blocking mode and it might block forever preventing the process to terminate and restart.

Hey @aivarsk, thanks for taking the time to open this -- this would definitely be good to add. I'll take a look.
