[ upstream commit 9e4d84b ]

The Kubernetes' client User-Agent was never set and it would always
fallback to the default value. This commit fixes this issue and now all
Cilium components will correctly present their User-Agent.

[ upstream commit f6f2406 ]

coredns < 1.7.0 has a bug that makes the services resolution to become
out-of-sync with the last state from Kubernetes in case coredns
suffers from a disconnection with kube-apiserver [1]. This bug is fixed on
all versions equal and above 1.7.0. [2]

In our CI this affects all Kubernetes jobs 1.18 and below and can result
in flaky tests that have the result in the following similar logs:

```
service IP retrieved from DNS (10.101.253.144) does not match the IP for the service stored in Kubernetes (10.108.15.225)
```
