Add annotation support for juju models

[kot0dama]

Requirements

We need to be able to annotate to a Juju model with tag-like key=value properties.
Would it be possible to add the annotation feature support to Juju Terraform provider?

Something like:

resource "juju_model" "mymodel" {
  annotations {
    "slo.level": "2"
    "slo.rto": "12h"
    "owner": "<user id>"
  }
}

Thank you!

Urgency

Required by a customer, please add it now!

Hi. Thank you for the report. We have discussed your request and we will implement the requested feature. However due to the release schedule it might not make it into the 0.18.0 release, so we are currently aiming for 0.19.0, which will be released in April.
