Transifex Native: Custom keys in Python & Django SDK

We have some exciting news to share!

From now on, you have the option to define custom keys for strings in Python and Django.

Developers can use the special _key parameter in order to set a custom key, instead of using the one automatically generated by the source string and the context.

You can also amend the --verbose option of the push command so that it always prints the key of each string.
