[FEATURE]: Allow for select statement in insert values clause

[DanielBaulig]

Describe what you want

Maybe I am doing something wrong, but it doesn't appear to be possible to pass a select statement to the values clause of an insert statement like follows

db.insert(table).values(db.select().from(otherTable).where(condition));

Obviously assuming that otherTable's schema sufficiently matches to populate rows in table.

This seems like such an obvious feature that I am suspecting it's possible and I'm just not calling it correctly.
