Changes in DID Spec format: controller and verificationMethod are implemented

[arnabghose997]

CHANGELOG:

• controller field has been added
• publicKeyStruct has been renamed to VerificationMethod with changes in its fields
• name and type fields are removed as they don't conform with latest DID Spec
• The current implementatition takes in the verification key and checks if that belongs to either of the DID controllers. If so, then the signature is valid, which is an approach as opposed to the earlier implementation where all the signatures of DIDs present in DID Controllers were expected. This needs to be verified.

Tests for DID Controller

Firstly, three users are created by running tests/create_users.sh

TC 1: Adding User-1's DID to User-2's controller

TC Expectation: It should update User-2's controller to have User-1's DID

TC Expectation: It should update User-2's DIDDoc, since User-1, being part of User-2's controller, now has the authority to make changes.

TC Expectation: It should fail because User-3's DID is not part of User-2's controller, and hence it doesn't have the authority to update changes.

TC Expectation: It should update, as User-2 has the permission to make changes. Since, User-3 is now part of User-2's controller group, running TC-3 would run successfully.
