bug: Modifying VLAN on a TF-managed tenant deletes other manually created tenants

[leonseng]

Encountered bug where modifying VLAN on a TF-managed tenant deletes other manually created tenants

Version

Platform: r4000, r5000
F5OS-A 1.8.0
Provider version: 1.8.0

Steps to reproduce

1. Manually create a tenant via F5OS WebUI, e.g. named lseng-manual-bigip
2. Use Terraform to deploy a new tenant, e.g. lseng-tf-bigip, with some VLANs.

resource "f5os_tenant" "bigip" {
        name              = lseng-tf-bigip
        image_name        = "BIGIP-17.1.1.3-0.0.5.ALL-F5OS.qcow2.zip.bundle"
        mgmt_ip           = "10.176.10.250"
        mgmt_gateway      = "10.176.10.1"
        mgmt_prefix       = 24
        type              = "BIG-IP"
        cpu_cores         = 4
        memory            = 12288
        nodes             = [1]
        vlans             = [100, 200]
        cryptos           = "enabled"
        running_state     = "deployed"
        virtual_disk_size = 87
}

3. Use Terraform to modify VLAN assigned to lseng-tf-bigip, e.g. delete vlan 200

resource "f5os_tenant" "bigip" {
        name              = lseng-tf-bigip
        image_name        = "BIGIP-17.1.1.3-0.0.5.ALL-F5OS.qcow2.zip.bundle"
        mgmt_ip           = "10.176.10.250"
        mgmt_gateway      = "10.176.10.1"
        mgmt_prefix       = 24
        type              = "BIG-IP"
        cpu_cores         = 4
        memory            = 12288
        nodes             = [1]
        vlans             = [100]
        cryptos           = "enabled"
        running_state     = "deployed"
        virtual_disk_size = 87
}

4. Observe manually created tenant lseng-manual-bigip deleted.

Full Terraform logs with debug flag enabled:

tf.log

Looking at the TF logs, I noticed the provider does a PUT to /f5-tenants:tenants with request body containing only the tenant that is managed by TF, which could be why other tenants not managed by TF were deleted

Hi,
I got this issue even with TF managed Tenant as well.
