Implement MasterService

[thangchung]

To support the multi-tenancy architecture, we need to have a way to manage the Master metadata for all the services.

Acceptance Criteria:

• We can run the MasterService console app
• We can sign into the application via the ApiGateway with the X-TenantId in the header of the request
• We can log in successfully and access to the specific data of the X-TenantId
