Add an acceptance test for binding database instances (#3424)

## Why
<!-- Why are these changes needed? Provide the context that the reviewer
might be missing.
For example, were there any decisions behind the change that are not
reflected in the code itself? -->
The new test validates that `bind` works for the `database_instances`
resources.

## Tests
<!-- How have you tested the changes? -->

<!-- If your PR needs to be included in the release notes for next
release,
add a separate entry in NEXT_CHANGELOG.md as part of your PR. -->
