If Platform Proxy is set, it can't be explicitly unset in replications

[OliverOlg]

Describe the bug
If you have a platform Proxy configured leaving the proxy empty or '= null' in the local_repository_multi_replication will result in the Platform default proxy being set. It's not possible to have no proxy set in this scenario, since artifactory will default to setting the platform proxy.

resource "artifactory_local_repository_multi_replication" "repo-local" {
    repo_key = "repo-local"
    cron_exp = "0 0 12 * * ? *"
    enable_event_replication = true

    replication {
        enabled = true
        url = "https://remote.artifactory/artifactory/repo-local"
        username = user
        password = password
        sync_deletes = true
        sync_statistics = true
        sync_properties = true
        # proxy = null
    }
}

Requirements for and issue

• A description of the bug
• A fully functioning terraform snippet that can be copy&pasted (no outside files or ENV vars unless that's part of the issue). If this is not supplied, this issue will likely be closed without any effort expended.
• Your version of artifactory (you can curl it at $host/artifactory/api/system/version
  7.84.20
• Your version of terraform
  Terraform v1.5.7
• Your version of terraform provider
  12.1.0, but this hasn't worked in 9.3.0 either

Expected behavior
Setting proxy = null should result in the replication having no proxy.

Additional context
Since the provider does not implement the disableProxy that is available since 7.41.7 in the replication json
, it's not possible to create a replication that explicitly does not use a proxy.

@OliverOlg Thanks for the report. I've added this to our plan. Most likely I'll add the attribute disable_proxy to support your request.
