[Improve][Connector] Change path_list option setting using concating string with comma , to string list for FtpConnector

[Jake-00]

Description

For FtpConnector, currently we can specify directories to read by setting configuration json file using option path_list, but it can't specify several files' path to read.

Suggetion:

1. currently path_list specify a string contains path list, it is better to change to specify a string list like below
2. update documentation of FtpCoinnector

"reader": {
      "path_list": ["/data/json/upload1/test1.json", "/data/json/upload2/"]
}

@Jake-00 Thanks for your issue, you suggestion is we just not support directories right, we can use file path directly?

[Jake-00]

@hk-lrzy To read directories already support, but to read multiple specified files do not support yet.

I see, can you use same parameter to support? like we check the path is file or directory, if directory we support to list it and if it is file we support read it directly.

I don't want to add parameter because user need to know use which one, it's not necessary for user.

Sounds more reasonable, shall I change the issue description?

Sure~

When diving deeper in FtpConnector, it already supports to read specified files and directories. Issue description is wrong and I change the description of this issue. Could we add tag good-first-issue?
