Create a credential from clients

[christad92]

Allow an authorised user to create an ouath credential from an existing or newly provisioned client. Users will type the scopes of permissions to be granted to the credential on behalf of the user. Also we have to make provisions for extra fields (API version and state) for oauth services that that require theses data elements.

Acceptance Criteria:

• [ ] I can create one or many credentials from a client
• [ ] I should be able to use the credential in a project

How to Validate: Using the client created, create a credential with the following information:

• email: expensive-kingfisher@example.com
• password: Fine-Mandrill-15
• state: oRlcM1xJNPOb7Hk9
• scopes: photo+offline_access

A successful implmentation should return a response that looks like this:

{
  "token_type": "Bearer",
  "expires_in": 86400,
  "access_token": "IY5P-22rxMVtG0g7ei5n4H5cviyqXgrAh3diN22TUawkynmwBHcP_jI3dIgN942vesiHxNVo",
  "scope": "photo offline_access",
  "refresh_token": "29kuYraO8P06TCDP490S_kbe"
}
