This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

Update Status and Lifecycle
software updates move through different status levels as the updates are being applied.
After adding an update (patch) to the storage area you must move it to the repository, which manages distribution for the cluster. From there, you can install the updates to the hosts that require them.
Some of the available updates may be required on controller hosts
only, while others may be required on worker or storage hosts. Use sw-patch
query-hosts to see which hosts are impacted by the newly applied
(or removed) updates. You can then use sw-patch host-install to update the software on
individual hosts.
To keep track of software update installation, you can use the sw-patch query
command.
~(keystone_admin)]$ sudo sw-patch query Patch ID Patch State =========== ============ -<nn>.<nn>_PATCH_0001 Applied
where <nn>.<nn> in the update filename is the release number.
This shows the 'Patch State' for each of the updates in the storage area:
Available-
An update in the Available state has been added to the storage area, but is not currently in the repository or installed on the hosts.
Partial-Apply-
An update in the Partial-Apply state has been added to the software updates repository using the
sw-patch applycommand, but has not been installed on all hosts that require it. It may have been installed on some but not others, or it may not have been installed on any hosts. If any reboot-required update is in a partial state (Partial-Apply or Partial-Remove), you cannot update the software on any given host without first locking it. If, for example, you had one reboot-required update and one in-service update, both in a Partial-Apply state and both applicable to node X, you cannot just install the non-reboot-required update to the unlocked node X. Applied-
An update in the Applied state has been installed on all hosts that require it.
You can use the sw-patch query-hosts command to see which hosts
are fully updated (Patch Current). This also shows which hosts require
reboot, either because they are not fully updated, or because they are
fully updated but not yet rebooted.
