Add Settings - Authorization to Backend

[jopache]

Will need to create the following table structure:
Blocked: #4 (authentication backend)

1. Permissions
   -- Id
   -- EnvironmentId
   -- ApplicationId
   -- UserId
   -- Role (1 = ReadSettings, 10 = WriteSettings, 20 = CreateChildApplication, 30 = CreateChildEnvironment) spaced out by 10 allows me to add things like decryptsettings in the future
   (NOTE: Think about these queries... this hierarchical data could get quite complex)

Will then need to tap in read/write endpoints to authorize against a new authorization service.

For now this will assume that a user has access to all applications/environments as there is some additional complexity to deal with there. Will do this by creating a test user as part of seed script with all access to root of both.
