Response time

[djstrong]

In the clean up process response time for each proxy could be calculated.

No need to. If proxy service provides this info, than it's ok. Don't think it's required during clean up process.

It is not required, but might be helpful for further filtering proxy list.

We also need to keep in mind that response time calculated once may be significantly changed in a short period.
