crimson/common: bring green_get() to interruptor

The rationale
=============
Calling `get()` on an unavailable future can result in yielding
the reactor, so -- from the interruptor's POV -- the interrupt
condition must be handled exactly like it is done for `yield()`.

Interruptor takes care about that but, at the moment, only for the
interruptible futures; there is mechanism for plain `seastar::future`.
This patch paves the way for handling them as well.

osd: don't build unnecessary parts of SnapMapper for crimson

This commits skips building two call-sites of `omap_get_iterator()`
of `ObjectStore` which are bypassing the `OSDriver` abstraction
layer.

1. `SnapMapper::convert_legacy()` likely never be needed by
crimson and we can leave it unchanged.

2. `SnapMapper::Subber` isn't needed right now but will be
needed in the future.
