In Code Climate, eslint-plugin-jsx-a11y v4.0.0 is used.
Therefore, it seems that a warning is displayed.

ref https://github.com/codeclimate/codeclimate-eslint/pull/273

* feat(babel): Strip prop types

* chore(babel): Indent

* fix(babel): Move babel-plugin-transform-react-remove-prop-types to dependencies

* Use babel-preset-env on Streaming Server

Change the streaming server to use babel-preset-env as well as asset compilation.
This shortens the load time at first boot.

* remove babel-plugin-lodash

* Remove Babel plugin for ES Modules

Processing of ES Modules is executed by Webpack.
Don't have to do it on Babel side.

* Add plugin for test

Use ES Class Fields & Static Properties (currently stage 2) for improve class outlook.

Added babel-plugin-transform-class-properties as a Babel plugin.

There are some dependencies that are no longer needed anymore.
As a result, it took more time to install the package than necessary.

I want to delete them and shorten the installation time.
