[BB-224] - Updating to 7.10.X and adding autoRollingUpgrade value + Jobs

Updating Elasticsearch and Kibana resources to version 7.10.0 and 7.10.2 respectively, the latest available in IronBank.

As a result of going from 7.9.X to 7.10.X Elasticsearch needs to perform a Rolling Upgrade.

Added templates to perform pre and post upgrade jobs if "autoRollingUpgrade: true" which will run the required curl commands against the Elasticsearch service in the cluster to prep and then finalize the upgrade.

Confirmed after a number (I lost track) of upgrades, that this will successfully upgrade a cluster without interaction as long as all shards migrate successfully which we have no control over anyways in the event ES has issues.

To-Do:

• Finalize Chart version bump to 0.2.X to more easily facilitate being able to check for these upgrade checks. (Discussion?)
• Populate CHANGELOG
• Make sure templates are cleaned up and don't look like "Charlie Carol Meme"
• BigBang upgrade job passes.
