etcd Integrates Continuous Fuzzing

In the last few months, the team at Ada Logics has worked on integrating continuous fuzzing into the etcd project. This was an effort focused on improving the security posture of etcd and ensuring a continued good experience for etcds users. The fuzzing integration involved enrolling etcd in the OSS-Fuzz project and writing a set of fuzzers that would bring the test coverage of etcd up to a mature level.
