Make sure Terragrunt commands can be configured with -lock=true

[dz-sourced]

This fixes #785

In the current implementation, when using Terragrunt binary instead of Terraform, Terratest explicitly passes -lock=false to the CLI.
This triggers a bug in Terraform (see issue for details on that), but also doesn't allow us to run integration tests with remote state
backend configured in the same way we would run actual deployment since Terraform uses -lock=true by default.

This change allows Options.Lock to be passed down to the Terragrunt apply-all and destroy-all commands.

Default behavior in Terratest does not change, since Options.Lock is still initialized to false, but at least we can control it now.

Sanity check: it doesn't look like you changed anything in RunTerraformCommandE... So is the fix that -lock=false is no longer hard-coded and is now read from options instead? Or is the fix that apply-all is part of TerraformCommandsWithLockSupport now?

[dz-sourced]

@brikis98 Yes, the fix is that -lock=false is no longer hardcoded and can be supplied via options, but for this to work with Terragrunt apply-all and destroy-all commands need to be added to the TerraformCommandsWithLockSupport because of this check here

lockSupported := collections.ListContains(TerraformCommandsWithLockSupport, commandType)

Ah, got it, thanks for explaining! Changes LGTM. I'll kick off tests now.

@brikis98 I see that a couple of tests failed, but they don't seem to be related to my PR. Is there anything I need to do on my end to sort this out?

[brikis98]

We just merged some test stability fixes. Could you pull in the latest from master and I'll re-run tests?

[dz-sourced]

@brikis98 I have merged the latest from the upstream master. Should be good to go for another tests run.

[brikis98]

Thanks! I just kicked off the tests again.

[brikis98]

There was one test failure, but it looks unrelated/transient, so I'm going to merge.
