Reload certificate chain when one of the signer certicate expired during IHS runtime

Supposed we have 2  intermediate CA certificates which have the same key identifier and same public key in IHS SSL keystore. These 2 certificates are still within their validity period, which is not uncommon when  a CA is rolling update their certificates.

The current behaviour is that, we do not have a guaranteed order of which CA certificate picked up for use. If it happens the "older" CA certificate is used by IHS to build the server certificate chain, and then that "older" CA certificate expires while IHS is running, all subsequent SSL handshake fails. There is no automatic recovery unless IHS restarts, even though actually a newer CA certificate is available from the keystore.

Opening this IDEA, to explore the possibility for IHS to automatically "refresh" the certificate chain during runtime without a full restart.
