* New certificate and secrete abstraction with certificate infrastructure and certificate/secret stores. * leak testing for certificate resources to validate new ref counting in every test assembly * Migration guide updated and documentation added for all * Remove IDisposable from Nodestate and UserIdentity. * UserCertificateTokenHandler now just points into certificate registry/stores, no dispose required * Fix CA2000 warnings and cleanup of other diagnostics, increase warning levels in .editorconfig
