[confmap] Allow more recursion and URI expansions (#10712)

#### Description
Bumps the limit of how much recursion we allow. This check is also
gating non-recursive expansions. We probably could separate these
concerns, but thats work that isn't really worthwhile, a simple constant
bump is simple and will cover most users. For the rest, there are
workarounds.
