Log attributes for proxy auto-config (PAC) in Pulse configuration

Per https://gitlab.com/openconnect/openconnect/-/issues/617#note_1413539553,
Pulse servers may send proxy auto-config information
(https://en.wikipedia.org/wiki/Proxy_auto-config) in two forms
in the main configuration packet:

- attr 0x4023 contains a URL where the PAC file can be downloaded
- attr 0x4009 contains the full contents of the PAC file (may
  be very large)
