 Description   

When you have a array to match for it would be nice if you could use it directly with the in operator instead of having to do lots of 'or' statements.

For example, if I want to fetch the facts foo1, foo2, foo3, foo4 & foo5 in the current API this needs:

["or", ["=", "name", "foo1"], ["=", "name", "foo2"], ["=", "name", "foo3"], ["=", "name", "foo4"], ["=", "name", "foo5"]]

With a array/list operator this could instead be:

["in", "name", ["array", ["foo1", "foo2", "foo3", "foo4", "foo5"]]]

the "in" operator already exists, so this was meant to say array/list operator. Like in that example: ["in", "name", ["array", ["foo1", "foo2", "foo3", "foo4", "foo5"]]]

This is going to be important for HA to reduce the number of requests a PDB makes during initial sync.
