Added vault support for sops encryption mechanism

[teamfighter]

This pull request related to #1562

As used go.mozilla.org/sops/v3 v3.5.0 does not support hashicorp vault, I bumped this go module to v3.6.1
Also added github.com/hashicorp/vault v1.6.2 to avoid ambiguous import error while building binary.
I ran go test -v ./..., here is the output in gist.

I hope provided information is enough to merge this PR.

@yorinasub17 @brikis98 any updates on this please?

Thanks for the PR! Apologies for the delay. We are super buried right now. We'll get to this as soon as we can.

This would be super useful.

@brikis98 Hello. Any updates?

[brikis98]

Thanks for your PR and your patience as we got around to reviewing this!

I see the updates to go.mod... But there should be a corresponding auto-generated update to go.sum as well. Could you include that in the PR?

@brikis98 I have updated go.sum, could you please check it.

Hi @teamfighter,

I have this issue here #1629.
To fix it I need SOPS 1.7.0 and I see here you are already upgrading SOPS to 1.6.1.

Could you bump it 1.7.0 on this PR? That way you would be fixing my problem too.

Thanks.

This will require additional testing. I'll try to do this today.

Please take a look.

[brikis98]

LGTM, thanks! I'll kick off tests now.

[teamfighter]

As I can see, unit tests are failed. Should I fix something? If so, what exactly?

I think this is the error:

# github.com/gruntwork-io/terragrunt/cli
cli/hclfmt_test.go:9:2: missing go.sum entry for module providing package github.com/gruntwork-io/terratest/modules/files (imported by github.com/gruntwork-io/terragrunt/cli); to add:

I executed go get -t github.com/gruntwork-io/terragrunt/cli, and pushed changed go.sum file.
Could you please kick-off tests again?

Re-running...
