Prototype - Storing the Hermes iOS tarballs on Maven.

[cortinico]

Summary

I'm not going to merge this as it is, this is mostly for discussions with the community for the sake of
RFC #508 react-native-community/discussions-and-proposals#508

Here I'm setting up a :ReactAndroid:external-artifacts Gradle module which is responsible of
uploading arbitrary artifacts to Maven (Central or any other repo).

In this specific example I'm uploading the Hermes iOS tarball which is 500+ Mb.
In this module I've configured the auth with Sonatype for publishing and the GPG signing of the artifacts.

Changelog

[Internal] [Changed] - Store the iOS Hermes tarball on Maven

Testing

I've tested this in a couple of ways:

Maven Local

1. Added the tarball in the expected location: ReactAndroid/external-artifacts/artifacts/hermes-ios.tar.gz
2. Publish to Maven Local with: ./gradlew :ReactAndroid:external-artifacts:publishToMavenLocal
3. Verify that the artifacts are there:

$ tree ~/.m2/repository/com/facebook/react/react-native-artifacts

/Users/ncor/.m2/repository/com/facebook/react/react-native-artifacts
├── 0.0.1
│   ├── react-native-artifacts-0.0.1-hermes-ios.gz
│   ├── react-native-artifacts-0.0.1-hermes-ios.gz.asc
│   ├── react-native-artifacts-0.0.1.pom
│   └── react-native-artifacts-0.0.1.pom.asc
└── maven-metadata-local.xml

Maven Central Staging Repository

I've pushed to a staging repository the tarball (so it's not released yet). It's currently available on:

https://oss.sonatype.org/service/local/repositories/comfacebook-3529/content/com/facebook/react/react-native-artifacts/0.0.1/react-native-artifacts-0.0.1-hermes-ios.tar.gz

(Link will expire in ~7 days).

If we were to release this to Maven Central, the final URL would be:
https://repo1.maven.org/maven2/com/facebook/react/react-native-artifacts/0.0.1/react-native-artifacts-0.0.1-hermes-ios.tar.gz

To publish you need to:

1. Make sure you have a Sonatype account which has push right on the com.facebook group
2. Make sure you have a GPG key + passphrase
3. Set the Gradle properties using environment variables as follows (or using the gradle.properties file):

export ORG_GRADLE_PROJECT_SONATYPE_USERNAME=<sonatype-username>
export ORG_GRADLE_PROJECT_SONATYPE_PASSWORD=<sonatype-password>
export ORG_GRADLE_PROJECT_SIGNING_KEY=$(cat ~/your-armored-private-key.pgp)
export ORG_GRADLE_PROJECT_SIGNING_PWD=<gpg-passphrase>

4. Publish with ./gradlew :ReactAndroid:external-artifacts:publishAllPublicationsToMavenCentralRepository

Closing as this was a prototype and it's effectively implemented
