Hardcoded sleep in `dnacenter_floor`, `dnacenter_building`, `dnacenter_area` resources

Prerequisites

• [x] Have you tested the operation in the API directly?
• [x] Do you have the latest Terraform provider version?
• [x] Review the compatibility matrix before opening an issue.

Describe the bug I noticed that deletion of dnacenter_floor resource is taking long time, looked at the resource code and found time.Sleep(1 * time.Minute) in resourceFloorDelete function. The same sleep can be found in _building and _area resources. Please remove it, I hope it is not necessary any more.

@fmunozmiranda you have removed delay in building resource, but forgot to do the same for area: https://github.com/cisco-en-programmability/terraform-provider-dnacenter/blob/860d4589a2bbaa683f3649f80c38579e0d3e2e1d/dnacenter/resource_area.go#L408 and floor: https://github.com/cisco-en-programmability/terraform-provider-dnacenter/blob/860d4589a2bbaa683f3649f80c38579e0d3e2e1d/dnacenter/resource_floor.go#L568
