github: DEPRECATE my.coding.github

Instead my.github.all should be used (still backward compatible)

The reasons are
a) I don't feel that grouping (i.e. my.coding.*) makes much sense
b) using .all pattern (same way as twitter) allows for more composable and cleaner separation of GDPR and API data

my/twitter/all.py
