Replaced hyphens with underscores in examples
project definition for all examples which had
hyphens in their project name. dpp-enrollee is
an exceptions because the name matches the
project directory name while the project
directory also contains hyphens.
the binary size check in example test was removed long time ago. Now we
have updated ttfw_idf to raise exception when performance standard is
not found. These fake performance check will be regarded as error.
Remove them now.
If mdns answer hasn't been received within timeout, Value error would be raised, but the mdns-server-thread would still run, blocking CI jobs. Fixed by moving the raise statement within try-finally block
Test services may cause confussion (and did cause some GitHub/forum issues). This update runs test services only when example executed in ci. Also host name is a simple config entry if executed outside of ci.
