Don't define DISALLOWED_SUFFIXES if already defined

[djberg96]

Prevents this warning while running specs, and might be good in general:

/app/models/metering.rb:5: warning: already initialized constant Metering::DISALLOWED_SUFFIXES

As mentioned in Gitter, can you just put the constant in the module itself?

[1] pry(main)> require 'active_support/all'
=> true
[2] pry(main)> module ModA; extend ActiveSupport::Concern; CONSTANT=[1,2,3]; end
=> [1, 2, 3]
[3] pry(main)> class ClassA; include ModA; end
=> ClassA
[4] pry(main)> ClassA::CONSTANT
=> [1, 2, 3]

@Fryguy ok, updated to to just define it normally.
