For OpenSIPS 3.x, set "client_protocol" to 1.0 in the json configuration
under the "sessions" section. The current default protocol version is 2.0.
Addresses #4339
The one from sessions takes an additional event alongside the
SessionFilter, while the one from agents will accept a CGREvent
instead of a simple originID string
The additional event sent to SessionSv1ReAuthorize will be merged
with the EventStart event from the matched session and can be used
when building server initiated requests from the *req map. The
initial packet which was initially inside *req, will be moved to
the *oreq ExtraDP (stands for original request).
Updated radigo library to latest version.
Updated RadiusAgent to satisfy the birpc client interface.
Added *radDAdiscMsg OrderedNavigableMap type field within AgentRequest.
This one is similar to *diamreq, as it is used for building RADIUS
server-initiated Disconnect Requests.
radReplyAppendAttributes: refactored to reflect that it can now be
used to also append attributes to request packets, not only reply.
Added bidirectional support for session related RadiusAgent methods.
For Dynamic Authorization to be possible, a new field was added within RadiusAgent
that holds dicts and secrets only for the clients that support it. They are used
to create the DA Client sending Disconnect Requests.
Added a new cache partition to store Access-Request packets with the purpose
of using them to build the Disconnect Requests. They are identified by sessionID.
It defaults to the value of 'Acct-Session-id'.
Added a predefined '*dmr' template as well as a 'dmr_template' config option within
the 'radius_agent' config section. This will map to a custom or to the predefined
template and will be used to build the Disconnect Request. By default, it doesn't
point to any template (this also means that the Access-Request packets will not be
cached).
Another option added to 'radius_agent' is 'client_da_addresses', which lists the
RADIUS clients supporting Dynamic Authorization. The key represents the host of
the client, while the value represents the address to which we will send the
Disconnect Request.
Added integration test.
Add ees_success_ids and ees_failed_ids fields in reader config. The
former will be used to set EeIDs when the event processing returns
no error, while the latter will be used otherwise.
Add config sanity checks for the added options.
Remove Processed opts and everything related to them since they should
not be used anymore.
Fixed test compilation errors caused by the change.
Implemented functionality that handles reconnecting to the amqp server
and reinitializing the amqp channel in case of errors and timeouts. This
is handled by a goroutine created in the client constructor (it also
handles the initial connect/init).
Reconnects and reinits will use a fibonacci backoff strategy, and the
attempt amount and max waiting interval can be adjusted by the
'reconnects' and 'max_reconnect_interval' config options.
Messages that fail processing are now dropped instead of being requeued,
preventing infinite processing loops. However, this means that the
messages are lost. Handling failed messages will need to be addressed
separately.
'concurrent_requests' will now set the prefetch count. Setting the
prefetch count using the Qos function was able to replace our old
approach that was using channels. Default value is 1024 which,
according to the rabbitmq docs, 'runs into the law of diminishing
returns'. The recommended value is between 100-300. Source:

Fix test compilation errors and failing tests caused by these changes.

HierarchyPath parser now returns nil when
the path is empty (instead of a string slice with one
EmptyString element).
If the prefix is set to true, when calling the AsString
method on a nil HierarchyPath, only the separator will
be returned. This avoids a nil expr error coming from
the xmlquery library.
Use the Query and QueryAll functions from the xmlquery
package to be able to handle the errors ourselves and
avoid panics.
Remove config default value for xml_root_path. The field
will remain commented in config_defaults for reference.
Add tests for HierarchyPath.AsString function.
Add comments for XmlProvider and xml_root_path opt.
