Make sure you have checked _all_ steps below.
### Jira
- [x] My PR addresses the following [Airflow
Jira](https://issues.apache.org/jira/browse/AIRFLOW/) issues and references
them in the PR title. For example, "\[AIRFLOW-XXX\] My Airflow PR"
- https://issues.apache.org/jira/browse/AIRFLOW-5230
- In case you are fixing a typo in the documentation you can prepend your
commit with \[AIRFLOW-XXX\], code changes always need a Jira issue.
- In case you are proposing a fundamental code change, you need to create
an Airflow Improvement Proposal
([AIP](https://cwiki.apache.org/confluence/display/AIRFLOW/Airflow+Improvements+Proposals)).
- In case you are adding a dependency, check if the license complies with
the [ASF 3rd Party License
Policy](https://www.apache.org/legal/resolved.html#category-x).
### Description
- [x] Here are some details about my PR, including screenshots of any UI
changes:
Following https://issues.apache.org/jira/browse/AIRFLOW-4835, I've also
refactored the template file loading functionality to:
- Avoid building multiple Jinja environments
- Avoid code duplication around `env.loader.get_source`
- Rename `resolve_template_files` to `load_template_files` which follows the
Jinja naming
- Support other collection types for storing template file paths (tuple,
namedtuple, dict and set)
- Add tests for all types
- Move related test from `core.py` to `test_baseoperator.py`
- Adhere to 110 char line length
- Add Pydoc
- Add typing
### Tests
- [x] My PR adds the following unit tests __OR__ does not need testing for
this extremely good reason:
Few tests in `test_baseoperator.py` to test providing template filepaths in
various data structures (dict, list, str, etc...), and moved a test from
`core.py` to `test_baseoperator.py`.
### Commits
- [ ] My commits all reference Jira issues in their subject lines, and I
have squashed multiple commits if they address the same issue. In addition, my
commits follow the guidelines from "[How to write a good git commit
message](http://chris.beams.io/posts/git-commit/)":
1. Subject is separated from body by a blank line
1. Subject is limited to 50 characters (not including Jira issue reference)
1. Subject does not end with a period
1. Subject uses the imperative mood ("add", not "adding")
1. Body wraps at 72 characters
1. Body explains "what" and "why", not "how"
### Documentation
- [ ] In case of new functionality, my PR adds documentation that describes
how to use it.
- All the public functions and the classes in the PR contain docstrings
that explain what it does
- If you implement backwards incompatible changes, please leave a note in
the [Updating.md](https://github.com/apache/airflow/blob/master/UPDATING.md) so
we can assign it to a appropriate release
### Code Quality
- [ ] Passes `flake8`
