Golang 1.13 introduced a change in test flag parsing:
> testing
> ...
> Testing flags are now registered in the new Init function, which is invoked by the generated main function for the test. As a result, testing flags are now only registered when running a test binary, and packages that call flag.Parse during package initialization may cause tests to fail.

Here, we ensure that e2e framework parsing occur in TestMain, by only
initializing Framework at Run invocation.
Go implicitly treats files ending with `_linux.go` as build tagged for
Linux only. This broke the e2e provisioning framework on macOS once we
tried importing it into the `e2e/consulacls` module.
Provide script for managing Consul ACLs on a TF provisioned cluster for
e2e testing. Script can be used to 'enable' or 'disable' Consul ACLs,
and automatically takes care of the bootstrapping process if necessary.
The bootstrapping process takes a long time, so we may need to
extend the overall e2e timeout (20 minutes seems fine).
Introduces basic tests for Consul Connect with ACLs.
This change allows for providing the -suite=<Name> flag when
running the e2e framework. If set, only the matching e2e/Framework.TestSuite.Component
will be run, and all ther suites will be skipped.
The e2e framework instantiates clients for Nomad/Consul but the
provisioning of the actual Nomad cluster is left to Terraform. The
Terraform provisioning process uses `remote-exec` to deploy specific
versions of Nomad so that we don't have to bake an AMI every time we
want to test a new version. But Terraform treats the resulting
instances as immutable, so we can't use the same tooling to update the
version of Nomad in-place. This is a prerequisite for upgrade testing.
This changeset extends the e2e framework to provide the option of
deploying Nomad (and, in the future, Consul/Vault) with specific
versions to running infrastructure. This initial implementation is
focused on deploying to a single cluster via `ssh` (because that's our
current need), but provides interfaces to hook the test run at the
start of the run, the start of each suite, or the start of a given
test case.
Terraform work includes:
* provides Terraform output that written to JSON used by the framework
to configure provisioning via `terraform output provisioning`.
* provides Terraform output that can be used by test operators to
configure their shell via `$(terraform output environment)`
* drops `remote-exec` provisioning steps from Terraform
* makes changes to the deployment scripts to ensure they can be run
multiple times w/ different versions against the same host.
