Deadpool & Tiberius simple impl

Just chaining configs from tiberius and create pool.

```rust use deadpool_tiberius;

[tokio::main]

async fn main() -> Result<()> { let pool = deadpooltiberius::Manager::new() .host("localhost") .authentication(AuthMethod::sqlserver("test", "test")) .database("database1") .trustcert() .createpool()?;

let conn = pool.get().await?;
let rows = conn.simple_query("SELECT 1");

} ```
