Add TLS certificate information to pwping

ProjectWise now requires TLS certificates on all servers but there are no good tools for verifying the certificates that are installed on a server, standard web based ones don't work with ProjectWise servers.

Idea is to add an additional option in pwping that will display all certificate information in the chain of servers. It would be similar to the -c option for listing all caching information.

Useful info to know: Common & alternative names, Organization Name, validity dates

Perhaps with a verbose form that would show what protocols and cipher suites were actually negotiated.
