Issue to use thunder_file_ssl_cert_key (Resource) 1.1.0

[sleminov-tc]

I was using 0.5.21-beta version without any issues. However with major version change the interface of many resources had changed.
Wonder what is current way of uploading cert key pair to a10?

Previously
resource "thunder_file_ssl_cert_key" "cert_key" {
file = "filename.zip"
file_handle = "filename.zip"
file_local_path = "path/to/filename.zip"
action = "import"
}

Now
resource "thunder_file_ssl_cert_key" "cert_key" {
host = "is this a10 device host"
name = "path/to/filename.zip"
path = "what this path is for"
protocol = "https"
use_mgmt_port = 1
}

Seems like there is no enough explanation in docs.

Please help
