## Description
Allows users to specify whether they want to
select folders by prefix or search behavior.
Search/contains behavior is the default case,
with prefix being an optional deviation if the
folder input is prepended with a '/' character.
Also, propagates the PrefixMatch setting to
all integration tests that rely on selecting only
the default folder in exchange.

swaps the corso go module from github.com/
alcionai/corso to github.com/alcionai/corso/src

go.sum files inside the repo.
All other changes in the repository update the
package imports to the new module path.
