v0.7.0

Made connection management better.

Now you can:

• Manually send a connection back to the connection pool.
• Use connection in async context management with the acquire method in ConnectionPool.
• Resize connection pool in runtime with resize method.
• Retrieve connection pool status with status method.

There was a problem with possible deadlock, but now it's solved.

We highly recommend you update your services with the new 0.7.0 version of the package.*
