Add OIDC integration tests
* Port OIDC integration tests to v2 * Move Tailscale old versions to TS2019 list * Remove Alpine Linux container * Updated changelog * Releases: use flavor to set the tag suffix * Added more debug messages in OIDC registration * Added more logging * Do not strip nodekey prefix on handle expired * Updated changelog * Add WithHostnameAsServerURL option func * Reduce the number of namespaces and use hsic.WithHostnameAsServerURL * Linting fix * Fix linting issues * Wait for ready outside the up goroutine * Minor change in log message * Add prefix to env var * Remove unused env var Co-authored-by: Juan Font <juan.font@esa.int> Co-authored-by: Steven Honson <steven@honson.id.au> Co-authored-by: Kristoffer Dalby <kristoffer@dalby.cc>
