memsql-python doesn't work with newest mysqlclient

[tomasz-at-nira]

Issue:
There has been a rename of parameters in connect() in mysqlclient
PyMySQL/mysqlclient#513

Installing latest memsql-python in a new python environment pulls latest mysqlclient. Code crashes.

Proposed solution:
Either patch memsql-python or freeze requirement for mysqlclient to use an older version.

+1 . I wasted 2 days figuring this out. Right now I manually updated 'db' to 'database' and 'passwd' to 'password' locally in database.py to unblock myself.
