e2e test: basic

[eguzki]

This is a integration test to validate basic happy path.

The Wasm configuration defines a set of rules for *.example.com.

Two (rate limiting) services are being defined, namely limitadorA and limitadorB.

One actionSet is defined that has two actions.
Each action should hit the same limitador instance, decrementing the counter twice.

"services": {
  "limitadorA": {
    "type": "ratelimit",
    "endpoint": "limitador",
    "failureMode": "deny"
  },
  "limitadorB": {
    "type": "ratelimit",
    "endpoint": "limitador",
    "failureMode": "deny"
  }
},
"actionSets": [
{
    "actions": [
        {
            "service": "limitadorA",
            "scope": "a",
            "data": [
                {
                    "expression": {
                        "key": "a",
                        "value": "1"
                    }
                }
            ]
        },
        {
            "service": "limitadorB",
            "scope": "a",
            "data": [
                {
                    "expression": {
                        "key": "a",
                        "value": "1"
                    }
                }
            ]
        }
    ]
}
]

And a new limit configuration

- namespace: basic
  max_value: 30
  seconds: 60
  conditions:
  - "a == '1'"
  variables: []

The test will run one request and expect the counter to be decremented by two.
The counter starts with 30, so after the request, the counter should be 28.
