In production, we recommend you run {es} on a dedicated host or as a primary service.
This adds that best practice to our setup documentation.

The current shrink API snippet doesn't show you how to remove replicas or reduce primary shards.
Rather than duplicate those instructions from the shrink API docs, this removes the snippet. A link to the shrink API and shrink ILM action docs is already provided.
It also updates a delete index API snippet to avoid wildcards. Wildcard expansion for the delete index API is disabled by default in 8.0.
* Mention match_only_text in disk usage docs
Previously we explained how to manually disable norms, freqs, and positions. We
now have a ready-made solution in the new `match_only_text` field type.

On the "Size your shards" page, the shard size recommendation assumes a time
series use case. Similarly, users shouldn't count nearly empty and rarely used
Enterprise Search system indices against the recommended shard count limit.
Closes#76328.
Changes:
* Revises the size your shards guide to use a 50GB shard guideline. This better aligns with our default in the ILM policy UI.
* Updates the language to indicate that the 50GB shard guideline is not a hard limit. Larger shards may work depending on the network and use case.
Reverts some changes added in #71367.
Today's network config docs are split into "Network", "HTTP" and
"Transport" pages, with unclear relationships between them. We often
encounter users with weird configs that indicate they don't really
understand how these settings all relate. In fact these pages are all
very interrelated, and the HTTP and Transport pages are almost all only
for advanced users. This commit brings these docs into a single page and
rewords some things to try and guide users away from the advanced
settings unless their configuration needs all the extra complexity.
It also adds a section entitled "Binding and publishing" which clarifies
the meanings of the `bind_host` and `publish_host` parameters. This is
also a common source of confusion amongst users.
It also clarifies that many of these settings accept a list of
addresses, and warns that this may not be what you want. Closes#67956.
