[Chore]Remove ConnectorV1 from the dev branch

[CalvinKirs]

V1 has not been updated for a long time, and it has also tended to be stable.
As a development branch, we are currently focusing on V2-related development, so I will remove it from dev branch.

Thx, update plugin-mapping.properties, As for bin/install-plugin.sh, I suggest we keep it, if some user wants to choose to mix, he can still do so, copy start (v1) and connector jar to lib, WDYT?

revert. But it doesn't really matter. I don't recommend maintaining this in dev. If necessary, a better way is to add it yourself. After all, we no longer intend to maintain this, we just provide a hybrid method.
