Bug 1803149: Rebase SDN to kubernetes 1.17.2

[juanluisvaladas]

• Merged the contents of Bug 1801737: drop firewalld monitoring, add better iptables monitor #39 into master

• Rebase SDN to Kubernetes 1.17.2

• Replaced go 1.12 for 1.13 in images.

• Removed unnecessary dependencies: During the migration to go modules
  a bunch of dependencies were defined explicitly so that we had an
  exact equivalent.

• OsdnProxy: Added OnNodeXxx functions so that it's compatible with
  service topology.

• HybridProxy: Added empty OnNodeXxx functions so that it implements
  the proxier interface. This proxy is not compatible with service
  topology.

Needs a review: The few things I didn't mention earlier:

We need openshift/release#7121 merged before make verify-deps can pass. This happens because go mod vendor produces different results in go 1.12 and go 1.13

This PR includes a commit which doesn't compile: 3b71b6b
Because according to the conversation today having every commit compilable is preferred but not mandatory I preferred preserving git blame over having everything compiling

I sneaked a exception for the directory .vscode in .gitignore

Verify-deps passed with go 1.13 which means after this is merged stuff will be mergeable again
