Bump kube-oidc-proxy to 0.3.0

Which issue(s) this PR fixes:
https://jira.d2iq.com/browse/D2IQ-82948

Special notes for your reviewer:
I tried to add to the chart things/changes that were introduced upstream since our last bump (to 0.2.0 in 1b9a4b392d13fa66f395eb854b57c962ca015969). I assume that the 0.2.0 bump did the same.

Tested with: mesosphere/kommander#1389 and manually with k20 - 1655a43c773009fb9d97cb940d7758d9370156b3, and latest konvoy (also manually).

The manual test consisted of launching the cluster, confirming that 0.3.0 was deployed, obtaining the token, and logging into the cluster and listing pods using it.

Does this PR introduce a user-facing change?:

Bumps kube-oidc-proxy to 0.3.0 to resolve "kubectl log" latency issues (COPS-7123)
