FIX: allow updating backend query compilers in place. (modin-project#67)

* FIX: Mutate client query compiler columns and index in the service.

Motivation: Align axis update semantics across query compilers. In the base
query compiler and even our service's query compiler, you can update the index
and columns in place. However, the service gives no way to update axes of a
query compiler.

Right now, for inplace updates, service exposes an extra method rename(), and
client query compiler uses this to get the id of a new compiler with updated
axis, and then updates its id ID of the new query compiler.

This change might be the first to make the service present a mutable interface
for a backend query compiler. That seems safe to me, except I had to make
copy() get a new query compiler copied from the old query compiler, because we
can't let updates to the new query compiler change the original (or vice versa).
