Objective

Description

Add the BitwardenClientInterface and related functions which will be used in integrations for mocks / testing. Update the cgo flags for multi-platform support via static linking.

Note

The -L /usr/local/lib -L /usr/lib locations were removed from the cgo lines. They only apply to Mac & Linux, and we are only currently supporting dynamic linking. If anyone is opposed to removing these please let me know, I figure we can add them back if we want to support dynamic linking in the future.

Before you submit

• Please add unit tests where it makes sense to do so
