// TestExecTLSCache asserts the semantics of the TLS cache when exec auth is used.
//
// In particular, when:
//   - multiple identical rest configs exist as distinct objects, and
//   - these rest configs use exec auth, and
//   - these rest configs are used to create distinct clientsets, then
//
// the underlying TLS config is shared between those clientsets.
