Split the configuration doc and review them again

[killme2008]

The configuration is really large right now, I think we can split it by modules or nodes:

https://docs.greptime.com/user-guide/deployments/configuration

And we must review the configuration when v0.9 is released.

The documentation for configuration file options is not intended for users to read options one by one, but to facilitate searching for certain within a single page, so configuration documents are usually large and list all options. For example, the documentation of MongoDB's configuration file options.

So we don't need to split it. I think we need to wrap the page navigation to let users find a certain option conveniently.

I will check the options for v0.9 manually, and hoping we can just link the configuration to Github in the future.
