convert cache key fields and cache ttl by status to their new formats

[jafowler]

This PR aims to add support for transforming attribute for the page rules cache_key_fields and cache_ttl_by_status actions.

For cache_key_fields we're looking to migrate

query_string {
    ignore = true // or
    ignore = false
} 

to

query_string {
   exclude = ["*"] // or
   include = ["*"]
} 

As for cache_ttl_by_status we're looking to transform

resource "cloudflare_page_rule" {
	actions = [ 
        {
		cache_ttl_by_status = [ 
                  {
			codes = "200-299"
			ttl = 300
		},
                {
                          codes = "300-399"
                          ttl = 60
                },
                {
                          codes = "400-403"
                          ttl = -1
                },
                {
                          codes = "404"
                          ttl = 30
                },
                {
                          codes = "405-499"
                          ttl = -1
                },
                {
                          codes = "500-599"
                          ttl = 0
                }
            ]
	}
  ]
}

to

resource "cloudflare_page_rule"{
  actions = {
    cache_ttl_by_status = {
        "100-149" = "no-cache"
        "150-199" = "no-store"
        "200-299" = 300
        "300-399" = 60
        "400-403" = -1
        "404" = 30
        "405-499" = -1
        "500-599" = 0
    }
  }
}

Proof cache_ttl_by_status works:

[jacobbednarz]

@jafowler is going to look into the cache_ttl_by_status = { ... } and cache_ttl_by_status = [ ... ] difference as there is a conflict here with what is expected and what is happening type wise.

[jafowler]

we've decided to drop the grit transforms for cache_ttl_by_status due to the complexity of the grit itself. We will document the changes and keep the grit transforms for cache_key_fields.
