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)
