Merge branch 'anders/diameter/string_decode/OTP-11952' into maint

* anders/diameter/string_decode/OTP-11952:
  Let examples override default service options
  Set {restrict_connections, false} in example server
  Set {string_decode, false} in examples
  Test {string_decode, false} in traffic suite
  Add service_opt() string_decode
  Strip potentially large terms when sending outgoing Diameter messages
  Improve language consistency in diameter(1)
