Allow multiple hosts for the provider to allow for HA

[philip-harvey]

Description

Currently the provider only supports one host. If this host is down or unreachable the Terraform will fail, even though there may be other IPA replicas that are online and reachable.

Potential Terraform Configuration

provider "freeipa" {
  hosts    = ["ipa1.example.test", "ipa2.example.test"]
  username = "admin"
  password = "123456789"
  insecure = true
}```

I don’t think this should be handled by the provider.
I would put a load balancer or some kind of failover system in front of the api and have the provider target it.
freeipa doesn’t like being behind a load balancer for host enrolment but it shouldn’t be an issue for the api. Be sure to enable sticky sessions or primary/backup config. You don’t want the api calls to end randomly on different servers. It would probably bring issues with the replication

@philip-harvey did you get a chace to try a reverse proxy in front of the ipa servers?

Hi @infra-monkey,
It seems like a lot of additional infrastructure to build a HA load balancer system to just load balance the API so that Terraform can call the API without failing when an IPA host is down, hence I have not followed this route.
