REST: GET: Use convertDBusToJSON

Use new_method_call() + async_send() to get back an sd_bus_message
from the org.freedesktop.DBus.Properties.GetAll call in the GET
handler, and then use convertDBusToJSON to extract any possible
property type instead of having to use a variant with all possible
property types defined ahead of time.

Tested: Did a get on several different paths, including one in
/org/open_power/ that had a signature of a(tx) that previously
didn't return anything.

Resolves openbmc/bmcweb#34
