Search before asking

• I had searched in the feature and found no similar feature requirement.

Motivation

1. Reduce the size of the packaged seatunnel;

Backgroud

I found that the dist module of the connector can be removed, and it is currently used in two scenarios:

1. [Improve][e2e] container only copy required connector jars #2681 Copy the connector dependencies to the container during the e2e test: this will copy all the connectors of the entire dist, which is unnecessary. I am going to use plugin.mapping and conf parsing to only copy the required connectors: ;
2. Use the maven plugin to copy all connectors to a specific folder when releasing: this is necessary, but it can be achieved in other ways; I am going to divide the dependencies of dist into multiple profiles and migrate them to seatunnel-dist ;

Usage Scenario

1. maven build
