Support for External mode of profile

[zhangcly]

Hi there,

I am a developer that is trying to migrate our code from AWS to AliCloud. When I use the external mode profile in terraform-provider-alicloud, it gives me an error.

Terraform Version

v1.5.7

Affected Resource(s)

Terraform Configuration Files

terraform file:

provider "alicloud" {
  profile = "product"
}
data "alicloud_caller_identity" "current" {
}
output "current_user_arn" {
  value = "${data.alicloud_caller_identity.current.id}"
}

~/.aliyun/config.json:

{
    "name": "product",
    "mode": "External",
    "access_key_id": "",
    "access_key_secret": "",
    "sts_token": "",
    "sts_region": "",
    "ram_role_name": "",
    "ram_role_arn": "",
    "ram_session_name": "",
    "source_profile": "",
    "private_key": "",
    "key_pair_name": "",
    "expired_seconds": 0,
    "verified": "",
    "region_id": "cn-beijing",
    "output_format": "json",
    "language": "zh",
    "site": "",
    "retry_timeout": 0,
    "connect_timeout": 0,
    "retry_count": 0,
    "process_command": "a command",
    "credentials_uri": "",
    "oidc_provider_arn": "",
    "oidc_token_file": ""
}

Debug Output

Panic Output

joe@JoedeMacBook-Air test % terraform apply         
╷
│ Error: configuring Terraform Alibaba Cloud Provider: no valid credential sources for Terraform Alibaba Cloud Provider found.
│ 
│ Please see https://registry.terraform.io/providers/aliyun/alicloud/latest/docs#authentication

Expected Behavior

When I use aliyun config runing with the config file ~/.aliyun/config.json, it works

joe@JoedeMacBook-Air test % aliyun sts GetCallerIdentity --profile product
{
	"AccountId": "xxxx",
	"Arn": "acs:ram::xxxx:assumed-role/daytona-developer/daytona",
	"IdentityType": "AssumedRoleUser",
	"PrincipalId": "xxxx:daytona",
	"RequestId": "xxxx",
	"RoleId": "xxxx"
}

and I expect that when running terraform scripts with this profile, it can aslo work.

Actual Behavior

When running terraform scripts with this profile, error occured with the message "Error: configuring Terraform Alibaba Cloud Provider: no valid credential sources for Terraform Alibaba Cloud Provider found.".
