Summary:
I created a new test project today using RN 0.60.3 and saw that prettier is now used with eslint. After looking at the `react-native-community` eslint config, I notice that it wasn't using the [recommended configuration](https://github.com/prettier/eslint-plugin-prettier#recommended-configuration) of `eslint-plugin-prettier`
This PR adds the `eslint-config-prettier` to avoid conflicts between eslint and prettier, it also adds the `prettier/react` config to avoid problems with the `eslint-plugin-react`.
## Changelog
[General] [Changed] - Use eslint-plugin-prettier recommended config
Pull Request resolved: https://github.com/facebook/react-native/pull/25674
Test Plan: - ✅ Ensure there is no difference on this repo (no ESLint errors, same number of warnings, and no changes when running prettier).

[General] [Fixed] - Add ErrorUtils to eslint globals
Pull Request resolved: https://github.com/facebook/react-native/pull/25947
Test Plan: Run eslint on a react native project using ErrorUtils. Eslint verification should pass.

Summary:
The `__mocks__` directories should be treated the same as `__tests__`
for the purpose of linting. See https://jestjs.io/docs/en/manual-mocks
## Changelog
[Internal] [Changed] - eslint: allow jest globals in `__mocks__` directories
Pull Request resolved: https://github.com/facebook/react-native/pull/25738
Test Plan:
I installed the updated package locally in my project and verified
that the `no-undef` rule no longer fires for references to `jest` in
`__mocks__` directories.

Summary:
This is an ESLint plugin that infers whether an import looks like a Haste module name. To keep the linter fast and simple, it does not look in the Haste map. Instead, it looks for uppercase characters in single-name import paths, since npm has disallowed uppercase letters in package names for a long time. There are some false negatives (e.g. "merge" is a Haste module and this linter rule would not pick it up) but those are about 1.1% of the module names in the RN repo, and unit tests and integration tests will fail anyway once Haste is turned off.
You can disable the lint rule on varying granular levels with ESLint's normal disabling/enabling mechanisms.
Also rewrote more Haste imports so that the linter passes (i.e. fixed lint errors as part of this PR).
## Changelog
[General] [Changed] - Add a lint rule to disallow Haste imports

Summary:
This fixes an issue where the Prettier config was set to the `fb` (Facebook) values for all users of the `react-native-community/eslint-config` package. This was due to [this line](https://github.com/facebook/react-native/blob/8f186b84aeeb2613bf6ae08f20a8547d40179007/packages/eslint-config-react-native-community/index.js#L219) in the config file.
It was causing issues like these:
* Errors when using newer versions of `eslint-plugin-prettier` (you had to use a version that was >1 year old): https://github.com/facebook/react-native/issues/24564
* Errors due to the Prettier parser being forced to be `flow` when using Typescript: https://github.com/typescript-eslint/typescript-eslint/issues/481
This PR:
* Changes that line to remove the explicit `fb` config so users can set their own.
* Moves the React Native Prettier config to `.prettierrc` so ESLint, Prettier, and code editors can all read from the same place.
* Upgrades both `prettier` and the `eslint-plugin-prettier` to the latest versions.
[General] [Fixed] - Stopped the Prettier config being set for all users of react-native-community/eslint-config

Summary:
This adds TypeScript support to the community ESLint config. Our babel preset supports TypeScript by default, so it's nice to have TypeScript support pre-configured in the ESLint config too.
Note: Users need to install `typescript` in their project for linting to work for TypeScript files.

Summary:
Existing glob might not work very well with `spec.js` and `test.js` files unless they're placed in `__tests__` directory. This PR aims to bring back the support of `jest` globals in these files, even if they're outside of `__tests__` directory.

Summary:
The goal of this PR is to enable eslint checks in the projects generated by `react-native init` command. I added `template/_eslintrc` file, that would be replaced in an initialized project with `.eslintrc` file. This PR comes in parallel with https://github.com/react-native-community/react-native-cli/pull/229
[General] [Added] - Added `.eslintrc` file to generated template.

Summary:
I was annoyed by warnings from yarn/npm about eslint peer dependencies not being met, so I dived in to try and get rid of some of them. Sometimes it meant bumping a plugin, but then that plugin needed a newer babel-eslint, so it was a dance.
Some we can't easily update to latest (eslint-plugin-prettier) because the rule format has changed a bit. Happy to do that in this PR if folks think its a good idea. eslint-config-fbjs itself needs to be updated and republished to eliminate the last few warnings.
There are a few new warnings (the repo wasn't linting cleanly for me from the start). I can fix those in this PR, or a separate one, based on people's preferences.
[internal] [chore] - Eliminate some peer dependency warnings and bump some eslint packages to latest.

Summary:
Landing D14472633 again which failed because of a metro-buck issue.
Latest CLI requires `reactNativePath` to be explicitly set when `react-native` is not present under `node_modules` (which is the case when running from source).
Fixes#23936
This PR also updates CLI to latest version and removes private calls to `findPlugins` (it's now exposed under public interface).
We also remove custom `rn-cli.config.js` options that are no longer needed that we have `--reactNativePath`. I added them a month ago as a temporary workaround.
