- The wrong type was being used in a list lookup function, resulting in the automatic
transformation being called erroneously and mangling the config.
- There was a left-over workaround still around which could still mangle the config.
This commit adds upgrade and downgrade hooks that are called when
upgrading from a bridge V1 to connector and action or the other way
around. The automatic translation is used if the callback is not
defined.
NOTE: Backported from master
This commit fixes the upgrade and downgrade strategy when upgrading
from a bridge V1 to connector and action or the other way around so that
the custom callbacks get the complete unchanged input instead of the
result of the automatic translation. The automatic translation is used
if the callback is not defined.
This commit changes how the `emqx_action_info` callback
`bridge_v1_to_action_fixup/1` works. It is now called after the
automatic upgrade instead of before. Since the full Bridge V1 config
might be needed to do the fixup, it is provided in a special field
`<<"__bridge_v1_conf__">>`. The `<<"__bridge_v1_conf__">>` field is
removed after the callback is called and can thus be ignored if it is
not needed.
This allows a n:1 relation between v1 bridge_types to action/connector types as
it's the case with mongodb for instance, where we had `mongodb_single`
`mongodb_sharded` etc and the new implementation will just have `mongodb`.
This commit adds callbacks to the emqx_action_info module for
doing fixes (such as changing a field name) after the automatic
split of a Bridge V1 config or the merge of connector and action
configs for the compatibility layer.

To make it consistent with the previous bridge behavior.
Also, introduces macros for resource status to avoid problems with typos.
Routing with v2 schema is actually more strict with respect to input to
`emqx_router` module routines. This causes Kafka consumer bridge to
crash when it tries to publish a message to a topic that looks like a
topic filter.
This removes the Kafka specific knowledge from emqx_bridge_v2 and
makes it possible to add new Bridge V2 bridges without modifying
the emqx_bridge application.
