Invoking job build with block=True fails on network errors

[cedrak]

ISSUE TYPE

• Bug Report

Jenkinsapi VERSION

0.3.11

Jenkins VERSION

2.176.3

SUMMARY

Blocking for build completion breaks when networking is unreliable.

EXPECTED RESULTS

I would expect that block would be (at least to some extent) resilient to network errors like in the case of queue.block_until_building.

ACTUAL RESULTS

Blocking for build completion breaks when Jenkins instance will respond with one non-200 response.

USEFUL INFORMATION

How to reproduce:

1. Make connection to Jenkins
2. Invoke job with block=True
3. During building on Jenkins receive 502 response from server

I could make PR, but I would need some assistance, to confirm if my solution proposition is correct.
