Support CI

[ShiKaiWi]

Thie project needs CI based on Github Actions to ensure the quality of development. And now about the CI what I can come up with is these jobs:

• python style check
• rust style check: (refer to actions in ceresdb)
  • rustfmt
  • clippy

And as for unit tests, now no unit test in this project has been provided and the test framework of the python project has not been decided yet so I suggest skipping the UT part in the CI for now.

@messense Would you like to take this task? And feel free to talk with us here or on slack if anything is unclear.

Adding style checks are easy. I was thinking more about adding CI to build Python wheels, I can do this along the way.

I do think the dependency issue I mentioned should be addressed first, otherwise CI could be terribly slow.

That all-in-one dependent delegate brings lots of unnecessary deps to other crates like this client. I've suffered from it already 😷

Opened apache/horaedb#103 for this.
