Adds a signal's metadata attributeflounder_5.99.2flounder/5.99.25.99.2
This adds a signal's metadata attribute which lets you store any kind and number of metadata attributes to your signal. These metadata are just reissued at the event emission without alteration. Special case of "unit" attribute which is kept as a signal attribute and not as a metadata because it is an intrinsic signal attribute that all signals should have. Bug-AGL: SPEC-1419 Change-Id: I531b4012ac9b22f312a4ccebc1a07a8d93129403 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
