Support of BlockingConnectionPool

[sileht]

Hi there,

aredis is lacking of BlockingConnectionPool.

Do this kind of feature could be accepted if I propose a Pull Request?
(and if it matches all the projects requirements and worked, of course :) )

I have started to take a look, the only blocking point I see is a small change into the ConnectionPool API.
ConnectionPool.get_connection() have to become async to be able to use asyncio.Queue()

Is that API change, ok ?

Another solution that would not break the API, would be to replace all get_connection() calls with something like:

conn = pool.get_connection()
if asyncio.iscoroutine(conn):
    conn = await conn

Here an idea of what it will looks like: #190

Any updates?
