tr is cheaper to run than gsub

Here is a little benchmark example :

require 'benchmark'

test_string = "namespace/example_services"

Benchmark.bm(10) do |x|
  x.report("gsub:") do
    1_000_000.times do
      test_string.gsub(/\//, "--").gsub("_", "-")
    end
  end

  x.report("tr:") do
    1_000_000.times do
      test_string.gsub(/\//, "--").tr("_", "-")
    end
  end
end

                 user     system      total        real
gsub:        1.128953   0.006334   1.135287 (  1.135361)
tr:          0.867549   0.004827   0.872376 (  0.872377)


          Use tr instead of gsub
