statics: Remove unneeded (and kinda odd) static str's

[kallisti5]

• These make non-static str database names ackward to use

congrats!

66Origin doesn't seem interested in maintaining Sofa, so you get my PR's ;-)

Had a quick discussion in rust channels about this.. these static str's are really weird, and add a ton of un-needed complexity around non static (aka non- "databasename") values.

Here's an example common error:

error[E0759]: cannot infer an appropriate lifetime
--> src/deploymentdb/mod.rs:5:19
|
5 | pub async fn open(name: &str)
|                   ^^^^  ---- this data with an anonymous lifetime `'_`...
|                   |
|                   ...is captured here...
...
8 |     client.db(name.clone()).await
|               ------------ ...and is required to live as long as `'static` here

Sorry this took a while, but I agree that these are a bit awkward. Let me merge this request.
