Increase highlighting for items that cannot be changed once set.

https://docs.couchbase.com/operator/1.2/couchbase-cluster-config.html

There are a number of options, such as Name and Services that cannot be changed once set. Although this is indicated in the text, it is usually the last sentence in the description. I think it would improve the readability of the documentation if such options had this limitation included, possibly in italicised bold, as the first line of the description, to highlight the importance of setting this correctly in the first instance.
