SRCH-2187 Update newrelic_rpm for ASIS (#102)

* SRCH-2187 Update newrelic in ASIS

Changed newrelic_rpm to 6.15.0 and ran `bundle update newrelic_rpm`

Added newrelic backport_fast_active_record_connection_lookup setting per newrelic's recommendations.
See release notes for newrelic_rpm 6.5 for details; basically, this setting should be on if at all possible, but it can interfere with other gems if the they monkey-patch ActiveRecord. This does not appear to be an issue for ASIS.

* Ran `bundle update`

SRCH-2404 use bundler 2.2.24 (#99)

- use ruby orb to install gems on CircleCi

SRCH-2317 bump puma (#96)

This is a follow-up to #94. That PR included the Gemfile.lock updates as a result of bundle update, but it did not include the Gemfile.lock updates as a result of bumping puma. This PR rights that wrong.
