google and image modules are synchronous

[freepizzas-dev]

The current libraries used for the google and the image modules contain synchronous web requests.

This means the bot doesn't perform optimally with a lot of users. Since these modules are driven by third-party libraries, it's not trivial to make these modules asynchronous and non-blocking.

Possible solutions:

• rewrite the necessary scrapers ourselves and remove sync blocking (probably easier for the image module)
• find async libraries to replace the ones we're already using (probably easier for the google module)
