Not setting the host name led the Go HTTP client to expect a certificate with a DNS-resolvable name. Since Nomad uses
${role}.${region}.nomad
names ephemeral dir migrations were broken when TLS was enabled.Added an e2e test to ensure this doesn't break again as it's very difficult to test and the TLS configuration is very easy to get wrong. Added new certificates for the test as our existing certificates allow
localhost,127.0.0.1
which means this bug isn't triggered as those are valid hostnames.Snuck a little commit in that fixes a race.
