Claims should be as much use-case agnostic as possible

[Sgitario]

At the moment, the Claim entity has the following properties:

• name
• serviceRequested
• type
• database
• category (will be included in Add a new field to define the category of the service (Sql, NoSql, ...) #201)
• ... among others

However, the database property is too database-specific and should be added using the key-value parameter (part of the credential entity). Also, the type property should be populated via a select with a set of options (the ones supported by the Service Binding logic).

My proposal is:

• Remove the database property
• Populate the type property using a select in the Claims form.

I agree with you that is too database-specific so yes, we should have it in the Credential#params.
Regarding the type, ok for having a dropDown list
