Allow more than 100 posts per page in queries

[rmccue]

100 posts per page is a pretty low limit really, and in actuality we can allow probably another order of magnitude here. The 100 per page decision in the REST API that we made was on the basis that each could embed other items, so 100 would actually be many more than 100 queries.

In custom code though, that's not necessarily the case, and allowing more would not necessarily be a problem. As an example, the sitemaps in WP core could query up to 2000 posts at a time, and that's probably not going to be an issue; see humanmade/altis-seo#38 (comment)

Should we increase this limit?

Since the limit (of currently 100 posts) is stored in a public property, it can be adapted on a per-project basis.

Do you mean we should do this in the HM standard already?

If yes, do you think 2000 is a good new value?
I'm wondering how often we make PHPCS ignore this rule...

I took a quick look at the HM repos, total of 19 ignores with these values:

1 x 150
1 x 250
1 x 300
6 x 500
5 x 1000
2 x 2000
1 x 5000
2 x 10000

I did another search for anything beyond 1000.

No custom code is using more than 1000, and only a handful of third-party plugins are using more. I think changing the allowed maximum value to 1000 shuold be fine, but we could also go for something higher.

Thoughts?
