add the -refresh option to plan and apply

[jdamata]

-refresh=true - Update the state for each resource prior to planning and applying. This has no effect if a plan file is given directly to apply.

#116

@jdamata First I'm not sure this PR is related to #116 since you are passing an arg to commands vs running the terraform refresh command itself (https://www.terraform.io/docs/commands/refresh.html).

Also, looking at the PR it seems this only allows disabling refresh ... there is no option for enabling it. I'm guessing that's because it's enabled by default?

Just curious the use-case to disable it when running apply/plan. No one has needed/wanted this until now.

Ah yah. I misread the issue.

Correct. Its enabled by default.

I'm utilizing the cloudflare terraform provider and have tons of resources. Cloudflare has rate limits on its API's. Our branching strategy runs terraform plan on feature/* branches and terraform apply on master. I find that with refresh enabled on feature branches, we hit the rate limit frequently.
