Add rollout option to osconfig patch deployment fixes https://github.com/hashicorp/terraform-provider-google/issues/7124

[cookejames]

If this PR is for Terraform, I acknowledge that I have:

• Searched through the issue tracker for an open issue that this either resolves or contributes to, commented on it to claim it, and written "fixes {url}" or "part of {url}" in this PR description. If there were no relevant open issues, I opened one and commented that I would like to work on it (not necessary for very small changes).
• Generated Terraform, and ran make test and make lint to ensure it passes unit and linter tests.
• Ensured that all new fields I added that can be set by a user appear in at least one example (for generated resources) or third_party test (for handwritten resources or update tests).
• Ran relevant acceptance tests (If the acceptance tests do not yet pass or you are unable to run them, please let your reviewer know).
• Read the Release Notes Guide before writing my release note below.

I have not tried to run the contributing tests yet. make test, and compiling the terraform module work.

make lint seems to run correctly for the osconfig module but has warning for other existing modules. These errors exist in master.

Hey @cookejames thanks for the contribution!

Can you add a test for this feature? It should be as easy as adding the rollout block to this file: https://github.com/GoogleCloudPlatform/magic-modules/blob/master/templates/terraform/examples/os_config_patch_deployment_full.tf.erb

which gets generated into the test for this resource.

[cookejames]

Thanks for the comments this is the first time I've worked on magic modules so didn't realise that was an automated test I thought it was more for generating documentation. I've added a test and fixed the other points you have mentioned.
