Require extendeddaemonset/api instead of whole EDS

[davidor]

What does this PR do?

This PR changes the go.mod so that it requires extendeddaemonset/api instead of the whole EDS project.
The new go.mod in EDS has been created in this PR: DataDog/extendeddaemonset#196

The operator was depending on the whole EDS project but in reality it only needs the EDS CRD defined in /api.

Hopefully this will generate less conflicts when upgrading the kubernetes libraries versions.

Describe your test plan

I don't think there's anything specific to test. The project should work exactly as before.
