Update version of eslint-loader used in cli-plugin-eslint

[Amndeep7]

What problem does this feature solve?

vue cli (cli-plugin-eslint) 4.4.6 uses eslint-loader 2.2.1. eslint-loader 2.2.1 does not support the 7.x release of eslint, which is the most recent version of eslint. The latest version of eslint-loader is 4.0.2 which does support the 7.x release of eslint. Can the version of eslint-loader used by cli-plugin-eslint be updated to the most recent version? Word of caution that doing so will drop support for versions of eslint less than 6.x.

What does the proposed API look like?

No api change, just version change in package.json for cli-plugin-eslint.

Well, seems that eslint-loader has been deprecated.

Maybe vue-cli v5 should migrate to eslint-webpack-plugin?

[Amndeep7]

I'm for it, but it seems like eslint-webpack-plugin only supports eslint v7 so it will be even more of a breaking change. It's also not a drop-in replacement so some changes to configuration will need to be made but the docs have a little bit of advice on how to migrate between them at least.

Should probably tag @sodatea as well to hear from them about when they think this should occur.
