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(?)

Who is depending on futures 0.1?

[GG2002]

It's futures-util, fbthrift-* used in rust-nebula and bb8 depends on futures and futures depends on futures-util. futures-utils/dependencies displayed that futures=0.1.25.

cargo tree is as follows:

├── bb8 v0.8.5
│   ├── async-trait v0.1.82 (proc-macro) (*)
│   ├── futures-util v0.3.30
│   │   ├── futures v0.1.31
│   │   ├── futures-channel v0.3.30
│   │   │   ├── futures-core v0.3.30
│   │   │   └── futures-sink v0.3.30

Does it need to be removed? I just don't know how to do it:(

[Xuanwo]

Seems someone has enabled futures-util's compat feature in wrong.

Ok, I got it: https://github.com/bk-rs/fbthrift-git-rs/blob/36ddca22a4aca8bbf02482ca20ff3fe525a24a87/Cargo.toml#L17

[GG2002]

vkill has contributed almost all of fbThrift's packages, can we remove this without communicating with him😇?

[Xuanwo]

I'm not sure. Can you contact @vkill? Or can we obtain write permission for the bk-rs organization? Maybe @wey-gu can help a bit.

[GG2002]

Perhaps it's possible, but I don't have high hopes. If I can establish a stable connection with vkill, I won't have to release a new rust-nebula crate. I will make modifications directly on his nebula-rust crate:(

[Xuanwo]

Hi, this could prevent us from making a new release.

[GG2002]

I'll publish rust-nebula crate in a few days, you can take a look at my code first.

OpenDAL has strict naming pattern for service names.

Please either use:

• nebulagraph / Nebulagraph

or

• nebula_graph / NebulaGraph

In every place this name showed up.
