rspec: Metadata server on Google App Engine displays IP address read from metadata server failed

Note: #763 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

Looks like this issue is flaky. :worried:

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (0211f1dc84faf7dca9924ac9fa37e570b5c5690e), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).

Seems to be happening consistently now.

The deployment tries four times, and fails with the following:

This is a bit puzzling to me. The symptom appears to be that it's not able to load sinatra.rb, but sinatra is definitely installed in the bundle:

Step #1: Step 11/14 : RUN bundle install --deployment --without="development test" && rbenv rehash
Step #1:  ---> Running in fadd4ed42787
Step #1: [DEPRECATED] The `--deployment` flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use `bundle config set deployment 'true'`, and stop using this flag
Step #1: Warning: the running version of Bundler (2.1.4) is older than the version that created the lockfile (2.3.20). We suggest you to upgrade to the version that created the lockfile by running `gem install bundler:2.3.20`.

It is probably worth trying to reproduce this in isolation by doing a clean deploy of the app.

Update - @bajajneha27 and I attempted to reproduce this issue, but we were able to deploy the app on joonix. I'll attempt this one more time during my next rotation.

This issue seems to be related to #https://github.com/teampoltergeist/poltergeist/issues/936

EDIT: The issue is unrelated to poltergeist, and is fixed in #1095. However, poltergeist is unmaintained since 2020 atleast, so we need to move away from it. I'll create a separate issue to track this.
