py-pymysql: updated to 0.10.0

v0.10.0

This version is the last version supporting Python 2.7.

* MariaDB ed25519 auth is supported.
* Python 3.4 support is dropped.
* Context manager interface is removed from `Connection`. It will be added
  with different meaning.
* MySQL warnings are not shown by default because many user report issue to
  PyMySQL issue tracker when they see warning. You need to call "SHOW \ 
WARNINGS"
  explicitly when you want to see warnings.
* Formatting of float object is changed from "3.14" to "3.14e0".
* Use cp1252 codec for latin1 charset.
* Fix decimal literal.
* TRUNCATED_WRONG_VALUE_FOR_FIELD, and ILLEGAL_VALUE_FOR_TYPE are now
  DataError instead of InternalError.
