[PATCH docs 12/18] ha-manager: crs: use headings for the scheduling points

[Daniel Kral <d.kral@proxmox.com>]

This is in preparation to be able to extend the existing entries with
more information and allows users to make permalinks to the specific
scheduling points.

 In every HA Manager round, the CRS checks whether any HA resources need a new
 node placement, which can be caused by any of the following scheduling points:
 
-- HA resource recovery (always active). When a node with active HA resources
-  fails, all its HA resources need to be recovered to other nodes. The CRS
-  algorithm will be used here to balance that recovery over the remaining nodes.
+HA resource recovery (always active)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-- HA rule config changes (always active). If a rule emposes different
-  constraints on the HA resources, the HA stack will use the CRS algorithm to
-  find a new target node for the HA resources affected by these rules depending
-  on the type of the new rules:

-** Node affinity rules: If a node affinity rule is created or HA resources/nodes
-   are added to an existing node affinity rule, the HA stack will use the CRS
-   algorithm to ensure that these HA resources are assigned according to their
-   node and priority constraints.

-** Positive resource affinity rules: If a positive resource affinity rule is
-   created or HA resources are added to an existing positive resource affinity
-   rule, the HA stack will use the CRS algorithm to ensure that these HA
-   resources are moved to a common node.
+If a rule emposes different constraints on the HA resources, the HA stack will
+use the CRS algorithm to find a new target node for the HA resources affected
+by these rules depending on the type of the new rules:
 
-** Negative resource affinity rules: If a negative resource affinity rule is
-   created or HA resources are added to an existing negative resource affinity
-   rule, the HA stack will use the CRS algorithm to ensure that these HA
-   resources are moved to separate nodes.

-- HA resources stopped -> start transition (opt-in). Requesting that a stopped
-  HA resource should be started is an good opportunity to check for the best
-  suited node as per the CRS algorithm, as moving stopped HA resources is
-  cheaper to do than moving them started, especially if their disk volumes
-  reside on shared storage. You can enable this by setting the
-  **`ha-rebalance-on-start`** CRS option in the datacenter config. You can
-  change that option also in the Web UI, under `Datacenter` -> `Options` ->
-  `Cluster Resource Scheduling`.
