```
The problem is that `rspec` loads `erb` for its configuration, which
loads `cgi/util` from system gems.
Then our tests change the `$LOAD_PATH` to make test gems installed in
tmp visible to `require`, and then they all require `cgi` as a
transitive dependency of `rack-test`, this time from `tmp` gems. This
causes system and test specific copies to be mixed together and these
warnings to be printed, but we have also observed failures in some tests
with errors like
> class variable @@accept_charset of CGI::Util is overtaken by CGI::Escape
This changes should also fix those failures.
The fix is to require all of `rack-test` (including `cgi`) before we
have changed the `$LOAD_PATH`. Because the `$LOAD_PATH` is unchanged,
RubyGems respects the version of `cgi` activated by RSpec, avoiding the
double loads.

- The command can either be run using:
1. `bundle doctor --ssl`
2. `bundle doctor ssl`
The later is most useful when you need to specify
custom ssl options (such as the verify mode or the
TLS version when running the diagnostic).
The implementation will follow in the next commits.
