Session support on CLI.

The CLI has been modified to support executing multiple commands through
the same session. A new 'connect' command has been added to establish
the session. A new 'disconnect' command has been added to destroy the
session. This way it's no longer necessary to specify the authentication
info in each commands:

  pki <auth info> connect
  pki user-find
  pki user-show caadmin
  pki disconnect

The old way of specifying the authentication info in each command will
continue to work, but the commands will be executed in separate sessions:

  pki <auth info> user-find
  pki <auth info> user-show caadmin
