feat: migrate to terraform plugin framework

[fabiomatavelli]

This PR will:

• Create the plugin framework provider
• Migrate the service offering resource to the plugin framework

[fabiomatavelli]

@CodeBleu @vishesh92 I started drafting the migration to the terraform plugin framework, base on the #71 , to see the effort to migrate the provider and resources. For that I've migrated the service offering resource. You can see the diff here.

I'm open to feedbacks on it.

@fabiomatavelli Just wondering the status of this? Is this dependent on the following being merged?

#71

[fabiomatavelli]

This is ready to be merged @CodeBleu , I just don't have the permission to merge it

I just still see it in "Draft" mode.

[fabiomatavelli]

Ah, sorry @CodeBleu , my bad, this is indeed waiting for #71

[CodeBleu]

@fabiomatavelli now that #71 is merged (🥳 ), I'm hoping that removing this from Draft mode, will be able to be merged, since @kiranchavala approved it.

[fabiomatavelli]

@CodeBleu I've removed the draft from it, but I think I'll need to rebase it

[fabiomatavelli]

@kiranchavala if you can approve the CIs to run again 🙏

@fabiomatavelli I have approved the github actions. Acceptance tests seems to be failing because of the below error:

 === RUN   TestAccServiceOfferingDataSource_basic
    data_source_cloudstack_service_offering_test.go:32: Step 1/1 error: Error running pre-apply plan: exit status 1
        
        Error: Invalid resource type
        
          on terraform_plugin_test.tf line 12, in resource "cloudstack_service_offering" "service-offering-resource":

        The provider hashicorp/cloudstack does not support resource type
        "cloudstack_service_offering".
        
        Did you intend to use the data source "cloudstack_service_offering"? If so,
        declare this using a "data" block instead of a "resource" block.

@vishesh92 @kiranchavala can you please review it again and re-approve the CI to run 🙏

I had to move the V6 (terraform plugin framework) to be tested with a muxed provider instead, as we still need to call resources/datasources in the V5 provider (terraform provider sdk).

@vishesh92 @kiranchavala Is this something that can be merged now? I feel like we were making good progress to get this provider over the hump with the new release of 0.5.0, and am hoping we can keep that momentum going and keep updating this project more frequently. With the #71 being merged and hopefully this one soon, I think this is really good for moving forward. There are some other PR's out there I think would be good to get merged as well, and hopefully we can get a new 0.6.0 release soon?
