Project title:

Datacenter and local file configuration conversion, export and import are supported via Apache APISIX CLI.

Background: 

Apache APISIX supports running in standalone mode. At this point, Apache APISIX will rely on the local configuration file `conf/apisix.yaml` for routing and policy settings.

Apache  APISIX CLI supports the conversion, import and export of data center and local file configuration data, making Apache APISIX easier to switch and apply between different environments and scenarios.

Task: 

Add two commands `bin/apisix conf_export` and `bin/apisix conf_import` to Apache APISIX CLI, and complete the conversion, import and export of remote data center and local file configuration data through the above commands.

Difficulty: Normal
Project size: ~350 hours.
