Fix the generated mocks

make test is currently failing because the generated mock references an undefined variable:

Error: mocks/service/k8s/Services.go:565:3: undefined: r1
Error: mocks/service/k8s/Services.go:567:3: undefined: r1
Error: mocks/service/k8s/Services.go:570:13: undefined: r1

This was probably introduced in merge from the upstream and not caught because we're still in the process of setting CI in this fork.

Fix the integration tests

The integration tests have also been broken since we added a configurable port to the Sentinels:

 # github.com/spotahome/redis-operator/test/integration/redisfailover_test [github.com/spotahome/redis-operator/test/integration/redisfailover.test]
Error: test/integration/redisfailover/creation_test.go:250:52: not enough arguments in call to c.redisClient.GetSentinelMonitor
