Update yapf to 0.29.0

[pyup-bot]

This PR updates yapf from 0.28.0 to 0.29.0.

Changelog

0.29.0

Added
- Add the `--quiet` flag to suppress output. The return code is 1 if there are
changes, similarly to the `--diff` flag.
- Add the `indent_closing_brackets` option. This is the same as the
`dedent_closing_brackets` option except the brackets are indented the same
as the previous line.
Changed
- Collect a parameter list into a single object. This allows us to track how a
parameter list is formatted, keeping state along the way. This helps when
supporting Python 3 type annotations.
- Catch and report `UnicodeDecodeError` exceptions.
- Improved description of .yapfignore syntax.
Fixed
- Format subscript lists so that splits are essentially free after a comma.
- Don't add a space between a string and its subscript.
- Extend discovery of '.style.yapf' & 'setup.cfg' files to search the root
directory as well.
- Make sure we have parameters before we start calculating penalties for
splitting them.
- Indicate if a class/function is nested to ensure blank lines when needed.
- Fix extra indentation in async-for else statement.
- A parameter list with no elements shouldn't count as exceeding the column
limit.
- When splitting all comma separated values, don't treat the ending bracket as
special.
- The "no blank lines between nested classes or functions" knob should only
apply to the first nested class or function, not all of them.
