Update cloud-provision to v0.6.8

• [ ] I have raised an issue to propose this change.

Description

Update cloud-provision to the latest version, v0.6.8.

Fixes HTTP tunnel provisioning for EC2.

How Has This Been Tested?

Changes to cloud-provision have been tested with inletsctl.

Tested E2E by exposing Traefik from a local cluster created with K3d to the internet.

Operator installation command used:

arkade install inlets-operator \
  --provider ec2 \
  --region eu-west-1 \
  --secret-key-file ~/.inlets/ec2-secret-key \
  --token-file ~/.inlets/ec2-access-key \
  --set 'image=ttl.sh/welteki/inlets-operator:0.17.4-1-gf98e43d'

How are existing users impacted? What migration steps/scripts do we need?

Users need to update their inlets-operator version. No additional steps are required.

Checklist:

I have:

• [ ] updated the documentation and/or roadmap (if required)
• [x] read the CONTRIBUTION guide
• [x] signed-off my commits with git commit -s

Changes to cloud-provision have been tested with inletsctl.

IMHO this needs to be tested independently since they work differently.

I tested this E2E now and exposed Traefik from a cluster created with K3d to the internet.
