Can we expose the timeout parameter to Repository.create_tree() to create large tree objects?

[rduve]

Currently, when trying to create a tree with large data there is a timeout error:

import github3

gh = github3.login(token=<token>)
repo = gh.repository(<org>, <repo>)
...
# Make big tree_data and tree_sha here.
...
tree = repo.create_tree(tree_data, tree_sha)

github3.exceptions.ConnectionError: <class 'requests.exceptions.ReadTimeout'>: A connection-level exception occurred: HTTPSConnectionPool(host='api.github.com', port=443): Read timed out. (read timeout=10)

Specifically, that tree_data object has 1610 blobs and is about 300 KB serialized.

Manually adding a timeout=60 to the self._post() in that function:

github3.py/src/github3/repos/repo.py

Line 1392 in 62367c9

json = self._json(self._post(url, data=data), 201)

allows the tree to successfully be created.

My goal is to not get the timeout when executing create_tree. Would it be a helpful addition to github3 if that timeout could be specified without patching the _post function? If not, would a PR that adds timeout to the create_tree function contract be welcome?
