requests to the agent, causing the agent to submit a CSR to the configured CA (generally Istiod). For other configuration,
Envoy will send [ADS](https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/operations/dynamic_configuration#aggregated-xds-ads)
requests to the agent, which will be forwarded to the configured discovery server (general Istiod).

## CA Flow

	sendEDSReqAndVerify := func(add, remove, expect []string) {

// authenticate authenticates the ADS request using the configured authenticators.
// Returns the validated principals or an error.
// If no authenticators are configured, or if the request is on a non-secure

// chain; or it can be set at build time. GOEXPERIMENT can also be set
// to "none", which disables any experiments that were enabled at
// make.bash time.
//
// Experiments are exposed to the build in the following ways:
//
// - Build tag goexperiment.x is set if experiment x (lower case) is
// enabled.
//
// - For each experiment x (in camel case), this package contains a
// boolean constant x and an integer constant xInt.

By default, the runner will attempt to find a Gradle distribution based on where the `GradleRunner` class was loaded from. That is, it is expected that the class was loaded from a Gradle distribution, as is the case when using the `gradleTestKit()` dependency declaration.

                This is useful when you want to have optional authentication.

                It is also useful when you want to have authentication that can be
                provided in one of multiple optional ways (for example, with OAuth2
                or in a cookie).

        Filing feature requests is one of the most popular ways to contribute to Guava.


        Be aware, though: most feature requests are not accepted, even if they're suggested by
        a full-time Guava team member. [Feedback](https://stackoverflow.com/a/4543114) from our
