Bug Report: local_example is only testing etcd topo in matrix build

[morgo]

Overview of the Issue

The GitHub actions workflow does this: https://github.com/vitessio/vitess/blob/42317c0ecf025c47fc2bcdc2eaf5267b93ca8d00/.github/workflows/local_example.yml#L89-L93

But the export on TOPO is not propagated to the container. You can see this by looking in any of the recent actions @ https://github.com/vitessio/vitess/actions?query=workflow%3Alocal_example

Expand "local_example" on one for zk/consul, and you'll see:

++ ETCD_SERVER=localhost:2379
++ TOPOLOGY_FLAGS='--topo_implementation etcd2 --topo_global_server_address localhost:2379 --topo_global_root /vitess/global'

Reproduction Steps

It looks like consul is actually broken. It looks like it has been deprecated for a while, so I am going to try removing it from the local_example instead.

This is the error when running consul:

export TOPO=consul
go run test.go -print-log -follow -keep-data -retry=1 local_example

I tried manually stepping through it, and the consul agent process is running / running consul-up.sh itself worked fine.

@morgo I recently added a bug fix that needed consul to run. I was able to add the test that passes in CI https://github.com/vitessio/vitess/pull/18434/files#diff-b521b09bb3810a48fe1c197b7468f5b40efc4e65b3622d434a94901392a2b918

Looks like these are two different ways of running consul.
