 Title: #620: [WIP] Fixing 6549
Action: opened

PR body:
"""
In order to fix https://pagure.io/freeipa/issue/6549. 

First of all, I tried at `ipaserver/server/install/replicainstall.py:1393`:
```python
try:
    domain_level = current_domain_level(remote_api)
    if domain_level != 0:
        conn.connect(bind_dn=ipaldap.DIRMAN_DN, bind_pw=config.dirman_password,
                 cacert=cafile)
    else:
        conn.connect(ccache=ccache)
```

However, the current_domain_level method was raising this exception:
```
ipa.ipapython.install.cli.install_tool(CompatServerReplicaInstall):
    ERROR    ldap2 is not connected (ldap2_140240602559056 in MainThread)
```

So, I created a connection first, then I check the domain level. 
If the domain level is 0 the connection is already created properly. If the domain level is not 0, then it should create using the ccache (how it was before). 

This PR fixes the error specified at the [bug #6549](https://pagure.io/freeipa/issue/6549), however it doesn't fix the entire ipa-replica-install process.  This is the output when running `sudo ipa-replica-install replica-info-vm-058-186.abc.idm.lab.eng.brq.redhat.com.gpg --skip-conncheck`
