Note: Doc team updates the current version of the documentation and the
two previous versions (n-2), but we address *only high-priority, or
customer-reported issues* for -2 releases in support.
Describe the changes in the doc and link to your dev story:

1. - [X] Mandatory: Add the required version to the Fix version/s field.

2. - [X] Mandatory: Choose the type of documentation change or review.

• [X] We need to add a new document to an existing section
• [X] We need a whole new section; this is a function not
  documented before and doesn't belong in any current section

3. - [X] *Mandatory: *Use the following link to open the doc and find where the
documentation update should go. Note: As the feature and doc is
understood and developed, this placement decision may change:

• Published doc: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.10
• Source: https://github.com/stolostron/rhacm-docs

4. - [ ] Mandatory for GA content:

5. - [X] Mandatory for bugs: What is the diff? Clearly define what the
problem is, what the change is, and link to the current documentation. Only
use this for a documentation bug.

New content (probably in this section, but I leave this to your discretion!) needs to be added to introduce hosted control planes as a feature that ACM customers who have installed the MCE operator have access to. This should be a new section in the "About MCE" chapter.
