v0.4.8-test1 (issue #569 BaseURL fix)

Test build for MKE-14280.

v0.4.7 + backport of Mirantis#576 (remove BaseURL), fixing issue Mirantis#569: streaming
exec/attach failed against Kubernetes >= 1.36 because the relative BaseURL
(no scheme) was resolved as HTTPS against cri-dockerd's plaintext listener.

Verified on MKE 3.10 / Kubernetes 1.37.1 / MCR 29.2.1: kubectl exec and
attach work with ExtendWebSocketsToKubelet at its upstream default.

Not for production use.

v0.9.9 (temp build, MKE-14565)

Temporary testing build for MKE-14565, replaces v0.4.7-dev1 with a plain-numeric version for orca's upgrade version-check test.
