Allow to use ~/.ovh.conf file to setup provider

[mcanevet]

OVH provides an ovh-cli tool that stores the credentials in ~/.ovh.conf in that format:

[default]
endpoint=ovh-eu

[ovh-eu]
application_key=<my_application_key>
application_secret=<my_application_secret>
consumer_key=<my_consumer_key>

[ovh-cli]

It would be great if the OVH provider could fetch credentials from this file.
For example:

provider "ovh" {
  profile = "ovh-eu"
}

Juste like the aws providers allows:

provider "aws" {
  profile = "my_profile"
}

error is "profile ="
the correct syntax is :
endpoint : "ovh-eu"
