feat(rest.packages.provider): add endpoint for .dp upload

[mattdibi]

This PR follows #4868 and adds the endpoint for .dp file upload. It leverages multipart/form-data under the hood.

Can be tested using:

export ADDRESS=<addr>
export USERNAME=<user>
export PASSWORD=<pass>

and then:

curl -X POST -k -u $USER:$PASSWORD --header 'Content-Type: multipart/form-data' --form 'file=@"/path/to/org.eclipse.kura.ai.triton.server-1.2.0.dp"' https://$ADDRESS/services/deploy/v2/_upload -v

Roadmap:

• Contribute deploy/v2 in its current form (feat(rest.packages.provider): add deploy/v2 Rest API #4868)
• Add endpoint for Deployment Package upload using multipart/form-data (feat(rest.packages.provider): add endpoint for .dp upload #4891)
• Add Depoloyment Package descriptor download and checking to install endpoint

Dependency:

This PR introduces a dependency on jersey-media-multipart v 2.27 which adds JAX-RS Integration with MIME MultiPart Message Formats. Eclipse Jersey is an Eclipse project therefore there should be no issue with Licensing.
