feat: Support NebulaGraph

[GG2002]

Which issue does this PR close?

Closes #4553.

Rationale for this change

What changes are included in this PR?

Support read, write, list, delete ops on NebulaGraph.

To access NebulaGraph, users must provide the username and password for NebulaGraph, as well as specify the space, tag, and the key field and value field of the tag.

Since each vertex in NebulaGraph must have a unique ID(called VID), but NebulaGraph lacks a self-incrementing ID, the unique IDs are generated using the Snowflake algorithm. Additionally, the set operation involves first delete existing original vertex, followed by inserting a new vertex.

NebulaGraph does not support the Blob type, hence Base64+string type is employed for file access. If it's supported in the future, just remove Base64.

Are there any user-facing changes?

No(?)

Hi, @GG2002. It might take us a while to complete the communication. Would you like to split this PR into parts so we can merge some of them first? I believe we can add the builder, config first without introduce the client impl in.
