Validate bags conform to bag profiles on import

[mikejritter]

Resolves: https://jira.lyrasis.org/browse/FCREPO-3184

• Adds profile validation functionality to BagProfile and ProfileValidationUtil
• Capture checksums for header files when exporting, ensuring that a bag will pass validation when imported

---

For testing:

1. Start a clean fedora repository
2. Create a binary resource in the new repository
3. Create a bag-config.yml for use during export

   bag-info.txt:
   Source-Organization: fcrepo-import-export
   Organization-Address: localhost
   External-Description: Sample bag export for fcrepo-3208

4. Run the exporter using the default profile and a directory of fcrepo-3184

   java -jar target/fcrepo-import-export-0.4.0-SNAPSHOT.jar --mode export --resource http://localhost:8080/fcrepo/rest --dir fcrepo-3184 --binaries --bag-profile default --bag-config bag-config.yml --user fedoraAdmin:secret3

5. Make adjustments to the exported bag so that it will no longer pass profile validation

   [fcrepo-import-export] $ cd fcrepo-3184 
   [fcrepo-3184] $ cp bag-info.txt bag-info.txt.bak
   [fcrepo-3184] $ sed -i '/Source-Organization/d' bag-info.txt
   [fcrepo-3184] $ sha1sum bag-info.txt >> tagmanifest-sha1.txt 
   [fcrepo-3184] $ vim tagmanifest-sha1.txt # remove the old sha1 digest
   [fcrepo-3184] $ sha1sum -c tagmanifest-sha1.txt 
   bag-info.txt: OK
   bagit.txt: OK

6. Start a fresh fedora repository
7. Try to import the bag, expecting that the profile validation will fail:

   java -Dfcrepo.log.importexport=DEBUG -jar target/fcrepo-import-export-0.4.0-SNAPSHOT.jar --mode import -r http://localhost:8080/fcrepo/rest --dir fcrepo-3184 --binaries -g default -G bag-config.yml -u fedoraAdmin:secret3

8. Move the original bag-info.txt back into place

   [fcrepo-import-export] $ cd fcrepo-3184 
   [fcrepo-3184] $ mv bag-info.txt.bak bag-info.txt
   [fcrepo-3184] $ sha1sum bag-info.txt >> tagmanifest-sha1.txt 
   [fcrepo-3184] $ vim tagmanifest-sha1.txt # remove the invalid sha1 digest

9. Run the import again, this time succeeding

   java -Dfcrepo.log.importexport=DEBUG -jar target/fcrepo-import-export-0.4.0-SNAPSHOT.jar --mode import -r http://localhost:8080/fcrepo/rest --dir fcrepo-3184 --binaries -g default -G bag-config.yml -u fedoraAdmin:secret3
