fixes#3084 adds events and improper chain flag
- splits cert resolution into root, legacy root + intermediate,
and third-party pool. Allowing the detection of client authentication
with incomplete chains if root + intermediate succeeds after root only fails
- adds `improperClientCertChain` to API Sessions and Current API Session.
Added for OIDC and legacy auth. Set to true when a client certificate is used
that was issued by the network and did not pass the root-only pool.
- adds endpoint POST /edge/management/v1/authenticator/{id}/extend
- adds endpoint POST /edge/management/v1/authenticator/{id}/extend-verify
- adds endpoint POST /edge/client/v1/authenticator/{id}/extend
- adds endpoint POST /edge/client/v1/authenticator/{id}/extend-verify
- add logic that allows a client endpoint to extend the valid period for
their current certificate authenticator
- requires clients to use their existing client cetificate for extension
- requires clients to verify they have received the new public key
- allows clients to use a new private key if desired
- allows only 1st party certificate authenticators to extend
- adds authenticatorId to apiSession for persistence, model, api model
- add session cert to already authenticated session on extend
- removes empty test stub
