Changed API of joonix/log

[jonsch318]

What happened:

when running go build with a project that uses agones 1.34.0 with a newer verison of joonix/log. It uses joonix.FluentdFormatter in pkg/util/runtime/runtime which changed now to joonix.NewFormatter() resulting in the following compilation error:

# agones.dev/agones/pkg/util/runtime
../../go/pkg/mod/agones.dev/agones@v1.34.0/pkg/util/runtime/runtime.go:39:30: undefined: joonix.FluentdFormatter

What you expected to happen:

building successfully.

How to reproduce it (as minimally and precisely as possible):

use i think any agenes project with the go agones and run go get -u ./... or just update the joonix/log package.

Anything else we need to know?:

Of course building works when using the specified version of joonix/log in the go.mod go mod edit -require github.com/joonix/log@v0.0.0-20180502111528-d2d3f2f4a806

Environment:

• Agones version: 1.34.0
• Kubernetes version (use kubectl version): none
• Cloud provider or hardware configuration: none
• Install method (yaml/helm): none/golang go get agones.dev/agones
• Troubleshooting guide log(s):
