Problem

Hello.

I'm running vector inside a proxyfied environment. I run with this global parameters:

proxy.enabled = true
proxy.http = "http://fpc:8080"
proxy.https = "http://fpc:8080"
proxy.no_proxy = "localhost,127.0.0.1"

And with this env variables:

# set | grep proxy
http_proxy=http://fpc:8080
https_proxy=http://fpc:8080
no_proxy=localhost,127.0.0.1

And vector, while starting correctly and doing the oauth token creation with GCP, tries to connect to something without using proxy:

[root@dv vector]# ss -antp | grep vector
LISTEN     0      128        127.0.0.1:8686        0.0.0.0:*     users:(("vector",pid=3021583,fd=10))
SYN-SENT   0      1      <localip>:37350  199.36.153.8:443   users:(("vector",pid=3021583,fd=9))

The IP 199.36 is for private access to GCP services.

Checking the code for the GCP pubsub source, it indeed looks like we are not using the proxy from the SourceContext.
