Oleksii Kliukin f18bb6eaaa Make errors in the cluster list function visible.
Sometimes the operator does not pick up clusters right away when
they are created. The change attempts to shed light on the
reason behind that.

Migrate only master pods. Migrate single masters. (#199)
Avoid migrating replica pods, since they will be handled by the
node draining anyway (the PDB specifies that only masters are to
be kept).

Allow migration of the single-pod clusters.

Improve behavior on node decomissionining (#184)
* Trigger the node migration on the lack of  the readiness label.

* Examine the node's readiness status on node add.

Make sure we don't miss the not ready node, especially when the
operator is killed during the migration.

Oleksii Kliukin 9720ac1f7e WIP: Hold the proper locks while examining the list of databases.
Introduce a new lock called specMu lock to protect the cluster spec.
This lock is held on update and sync, and when retrieving the spec in
the API code. There is no need to acquire it for cluster creation and
deletion: creation assigns the spec to the cluster before linking it to
the controller, and deletion just removes the cluster from the list in
the controller, both holding the global clustersMu Lock.

Oleksii Kliukin dd0affc390 Tweak our reaction to the cluster upgrade process.
Previously, the operator started to move the pods off the nodes to be
decomissioned by watching the eol_node_label value. Every new postgres
pod has been created with the anti-affinity to that label, making sure
that the pods being moved won't land on another to be decomissioned
node.

The changes introduce another label that indicates the ready node.  The
new pod affinity will esnure that the pod is only scheduled to the node
marked as ready, discarding the previous anti-affinity.  That way the
nodes can transition from the pending-decomission to the other statuses
(drained, terminating) without having pods suddently scaled to them.

In addition, rename the label that triggers the start of the upgrade
process to node_eol_label (for consistency with node_readiness_label)
and set its default vvalue to lifecycle-status:pending-decomission.
