To avoid having to pass around so many parameters to the hook package,
create a Request object to store all request-specific data. Update APIs
accordingly.
When attempting to match a JSON path for initial setup, it would be
helpful to know where the path failed. This change logs the failed
parameter node. For example, if you are trying to match path "a.b.d.e",
but you failed to include the "c" node, webhook will log an error
"parameter node not found: d.e" to assist in troubleshooting.
