Provide test proxy credentials for functional tests

[igor-sirotin]

We need test proxy credentials in the functional tests. In the future we'll mock the providers, but we can't do it quickly right now.

Functional tests will expect these env vars:

• STATUS_PROXY_USER
• STATUS_PROXY_PASSWORD

Tests side done here:

• Set proxy credentials from functional tests #6144

Are we sure the tests won't create a very large volume of requests? What's expected?

@jakubgs I can't promise anything about the usage 😐. But right now this is blocking functional test runs.

We will eventually, but it's not fast:

• mock the providers and try to make 0 requests
• implement "smart caching" on proxy

[jakubgs]

I see, that's fair, and indeed in a perfect world we'd mock everything, but it's understandable this is the simplest approach.

@mendelskiv93 could you please ensure the status-go tests have access to credentials to use proxy.test fleet.

But I would recommend creating a separate username and password for this purpose:
https://github.com/status-im/infra-proxy/blob/e815a56fd90fc34615201e87490c8a72ba11ab59/ansible/group_vars/proxy.test.yml#L13-L17

So it's easier to revoke this access in the future when we will probably create separate proxy.staging for tests like this.

@igor-sirotin Is there a way we can do:

      usernameVariable: 'STATUS_BUILD_PROXY_USER',
      passwordVariable: 'STATUS_BUILD_PROXY_PASSWORD'

like in status-mobile and status-desktop?

[igor-sirotin]

@mendelskiv93 if these are already available in status-go repo, then sure, we can use it 👍

[mendelskiv93]

@igor-sirotin yes they are!

[igor-sirotin]

@mendelskiv93 just in case, did you create separate credentials for this purpose?

This case is dangerous because we could potentially (but we'll prevent it as much as possible) leak the key in logs. So we must have dedicated username/password for simple revoke/rotate later.

[mendelskiv93]

@igor-sirotin yes I did, it will be used only by status-go.
Hopefully will not come to that but it can be easily removed.
