Reimplement Patroni support in new anydbver impl

[guriandoro]

We used to be able to have Patroni deployments:

./anydbver deploy \
node0 pg:13 patroni \
node1 pg:13 master:node0 patroni etcd-ip:node0 \
node2 pg:13 master:node0 patroni etcd-ip:node0 

But it seems after the migration to the new script, we are having issues:

[root@node1 ~]# patronictl -c /etc/patroni/cluster1-1.yml list
+ Cluster: stampede (7298832024534509405) ---------+----+-----------+-----------------+
| Member     | Host       | Role    | State        | TL | Lag in MB | Pending restart |
+------------+------------+---------+--------------+----+-----------+-----------------+
| cluster1-0 | 172.28.0.2 | Leader  | running      |  1 |           | *               |
| cluster1-1 | 172.28.0.3 | Replica | start failed |    |   unknown |                 |
+------------+------------+---------+--------------+----+-----------+-----------------+

The errors are due to:

[root@node1 ~]# cat /var/lib/pgsql/13/data/log/postgresql-Tue.log
...

Let me know if I can help with anything.

Correction, I was able to start one using implicit latest (15) versions:

./anydbver deploy node0 pg patroni node1 pg master:node0 patroni etcd-ip:node0 node2 pg master:node0 patroni etcd-ip:node0
