refactoring: testifysec/archivista-api as a pkg
The current "github.com/testifysec/archivista-api" was detached from the Archivista from the historical strategy by TestifySec. TestifySec donated the Archivista project to the in-toto project, which makes more sense to the API package being part of the Archivista source code. This commit adds "github.com/testifysec/archivista-api" as pkg in Archivista. Closes in-toto#113 Signed-off-by: Kairo de Araujo <[email protected]>
