First commit for libstorage testlib

Move TestBlockDevice into a standalone module and export it as a new rust_library.

Implement a builder pattern for flexible customizations with
reasonable defaults.

Remove duplicated implementations of TestBlockDevice in other test code
and replace uses with centralized implementation.

Note: the consumption and re-export of storage lib traits is an
unfortunate workaround for using Vec for block storage and scratch buffer.

Tests: all unit tests pass
