SDK not handeling connection timeout (Guzzle)

[ChrisTitos]

Describe the bug
The SDK and the GuzzleFeatureRequester do not seem to gracefully handle connection timeouts. I have noticed this problem during your current ongoing outage.

To reproduce
This behavior was noticed on an instance where we do not use relay proxy. So when the server cannot connect within 3 seconds (or whatever the timeout is) any call to variant() or getAllFlags or others, will result in an exception being thrown. From what I can see the SDK only handles response errors (40x, 50x)

Expected behavior
I expect the exception to be handled by the SDK, and the last known cache value to be used if possible.

SDK version
6.2.0

Thank you for bringing this to our attention. I will look into this and keep you updated once we have a fix in place.
