[Feature] Add Apache doris 2.0+ Database connector

[zfanswer]

Added support of Apache Doris database, tested chatdata chatdb functions on Doris 2.0, did not test 1.2.x, probably works :P.

and thanks a lot for PR #872, which provided tremendous assistance to this commit. I just modified a little bit, for the driver and some info retreival methods.

and I fixed the web UI of the doris db setup locally, but couldn't do as much as PR #889 , could reviewers help to fix the web ui as well?
