I checked this with: The prepared statement test currently fails (expected), and I had to re-run the mysql57.backup_mysqlctld test.. but it otherwise passes :-) |

A bug was discovered in this, where the scripts are not compatible with etcd 3.4. Since this changes to not install etcd if it's installed, it will break if the system has etcd 3.4 installed. I will followup and figure out what we need to fix. |

This is a revision of #5365
I have changed from strictly "make it a prerequisite" to "only install it if not present".
I resumed this PR because I noticed that we also distribute etcd in the Vitess packages. This PR is required to transition out of that. I think it is important to not ship 3rd party software (unless it is compiled in such as a library) because then Vitess is on the hook for security updates.
All the install and contributor guides already add $VTROOT/bin to $PATH, so switching to require it in path should work fine vs. ETCD_BINDIR.
