support execute_async

[24seconds]

Hello, while I'm using gluesql as a database (MemoryStorage),

Motivation

I found that glue blocks current thread until the execution is finished. For me, I need asynchronous execute function, not blocking one. So I wrote some code to support it.

Question

I saw so many test cases are written in this repo. So I also think I should write a test but I don't know where to start. Could you give me some guide? Thank you!

After the guide, I wrote the test in examples/api_usage.rs.
While doing that, I found 2 things and modified them with help from taehoon.

• mutable_api has some bug. It doens't run rest sqls, insert, drop etc. So I make them run in for loop
• In the glue.rs, plan function uses block_on internal. After talk with him, I changed this function as asynchronous

Added dedicated test for execute_async. Checked using tarpualin and it's 100% for glue.rs file.
