[tf][indexer] option for RDS to be publicly accessible

[rustielin]

New variable(s) to enable RDS to be publicly accessible, making it easier to plug into anlaytics tooling

• For testnet TF: indexer_db_publicly_accessible when enable_indexer = true, and will also determine which subnets to provision on
• For indexer TF: db_publicly_accessible

Also, includes a small fix for testnet REST API when validator-lite is enabled

Is the public access only protected by password? do we have any IP gating?

[rustielin]

Just added var that controls the security group: db_sources_ipv4

Bors help and documentation

Bors is a Github App used to manage merging of PRs in order to ensure that CI is always green. It does so by maintaining a Merge Queue. Once a PR reaches the head of the Merge Queue it is rebased on top of the latest version of the PR's base-branch (generally master) and then triggers CI. If CI comes back green the PR is then merged into the base-branch. Regardless of the outcome, the next PR is the queue is then processed.

General

• This project's Merge Queue can be found here.
• This project requires PRs to be Reviewed and Approved before they can be queued for merging.
• Before PR's can be merged they must be configured with "Allow edits from maintainers" enabled. This is needed for Bors to be able to update PR's in-place so that Github can properly recognize and mark them as "merged" once they've been merged into the upstream branch.
