Swap CI to Standalone Exe Only

TestProxyManager.java

Adjust function here

    private boolean proxyIsManual() {
        return Configuration.getGlobalConfiguration().get("PROXY_MANUAL_START") != null
    }

Then here.

        if (!proxyIsManual()) {
            TestProxyDownloader.installTestProxy(testClassPath);
        }

ci.tests.yml

Adjust code here to no longer run the proxy for you. Let the tests invoke. We still want to install so we can test-proxy restore -a <blah> before invoking the tests.

      - template: /eng/common/testproxy/test-proxy-tool.yml
        parameters:
          runProxy: false
