Change ON to IN for GRANT syntax

[d-roman-halliday]

GRANT Syntax change/clash

when running:

./sf_create_obj schema <DB>.<SCHEMA>

I got GRANT statements which didn't work, so I've changed the logic around. I can see that it was changed over in a previous change:

• 5d73b57
• d-roman-halliday@5d73b57

I'm not sure if this is a case of the previous change being a bug (it was changed in other places too then), or if we have a clash (in some cases we want it to be ON in this statement and in others we want IN).

Changes:

1. Adding standard python .gitignore
2. Adding requirements.txt for sf_create_obj functionality
3. Change ON to IN for GRANT syntax (for ./sf_create_obj schema <DB>.<SCHEMA>)
