The tools/gce/linux_kokoro_performance_worker_init.sh executes a script that installs a ruby version manager, RVM. For security reasons, this script relies on PGP keys from RVM maintainers.
It's execution failed at the installation of RVM, because the key for a new maintainer had not been received. This commit adds GPG key 7D2BAF1CF37B13E2069D6956105BD0E739499BDB for RVM's maintainer "pkuczynski". It results in the successful installation of rvm stable.
The current keyserver, hkp://keys.gnupg.net, is not one of the keyservers listed on https://rvm.io/rvm/security. When navigating to https://keys.gnupg.net in a browser, the server does not provide a way to search for keys without authenticating and redirecting to a strange domain. This commit also moves the script to use hkp://pgp.mit.edu, a listed keyserver that is maintained by MIT.
