The image is going to be pushed after the next commit.

You can use make trigger_ci to push an empty commit.

If you also want to run E2E tests, please add devnet-test-e2e label.

DO NOT MERGE main branch into issue-742-load-testing.
This has been branched off v0.0.7 to avoid protobuf changes.

The CI will now also run the e2e tests on devnet, which increases the time it takes to complete all CI checks.

You may need to run make trigger_ci to submit an empty commit that'll trigger the tests.

Added caching to avoid round-trips to the pocket RPC node. Tests passed.

Can't figure out why I get:

{"level":"error","service_id":"protocol-anvil","content_length":0,"content_type":"","method":"GET","url":"/?applicationAddr=pokt1pruh7jnjt3hjtjz0y7sund5am7q5v87q86ygvs","rpc_type":"REST","payload":"","application_addr":"pokt1pruh7jnjt3hjtjz0y7sund5am7q5v87q86ygvs","error":"getting current session: address: pokt1pruh7jnjt3hjtjz0y7sund5am7q5v87q86ygvs; serviceId: protocol-anvil; block height: 18426; error: [rpc error: code = Internal desc = grpc: error unmarshalling request: proto: illegal wireType 7]: error while trying to retrieve a session: internal error handling relay request","message":"failed handling relay"}

Doesn't appear to be related to the caching added in the PR.

Even though the branched is created off v0.0.7 release, it appears there's still some discrepancy between new build and the old one.

I'll continue throwing more resources. This will still affect the performance though.

Unlikely to need this as we're moving away from using appgate.
There's a similar functionality will be needed for relayminer, though. Will look into that as I hit that roadblock during the load test.
