Python 3 support

[PabloCastellano]

This tool is very useful and it would be awesome to have Python 3 support on it!

I believe this can be closed, as it's working fine with Python 3.7.5

@berislavlopac It won't work on Python 3.7.7.

This repo works well on Python 3.7.6.
It's just need to be updated on pip.

@cn007b I am late, but here is what I did to solve this problem with regex memcached_stats.

The problem is regex code, where clause 'ur' is deprecated since PEP 414. You need to use 'r' instead.
