In 0.10.2 (specifically 387b016) we added interpolation to group
service blocks and centralized the logic for task environment
interpolation. This wasn't also added to script checks, which caused a
regression where the IDs for script checks for services w/
interpolated fields (ex. the service name) didn't match the service ID
that was registered with Consul.
This changeset calls the same taskenv interpolation logic during
`script_check` configuration, and adds tests to reduce the risk of
future regressions by comparing the IDs of service hook and the check hook.
When parsing a config file which had the consul.timeout param set,
Nomad was reporting an error causing startup to fail. This seems
to be caused by the HCL decoder interpreting the timeout type as
an int rather than a string. This is caused by the struct
TimeoutHCL param having a hcl key of timeout alongside a Timeout
struct param of type time.Duration (int). Ensuring the decoder
ignores the Timeout struct param ensure the decoder runs
correctly.
If an alloc is being preempted and marked as evict, but the underlying
node is lost before the migration takes place, the allocation currently
stays as desired evict, status running forever, or until the node comes
back online.
This commit updates updateNonTerminalAllocsToLost to check for a
destired status of Evict as well as Stop when updating allocations on
tainted nodes.

Increase the shortened timeout after the first loop so that metrics
that take longer to come in aren't failing the test unnecessarily.
Move the check for empty alloc metrics into the loop so that if the
first values we get are empty we don't fail the test too early.

Fixes a bug where if a command flag parsing errors, the resulting error
and help usage messages get interleaved in unexpected and non-user
friendly way.
The reason is that we have flag parsing library effectively writes to
ui.Error in a goroutine. This is problematic: first, we lose the sequencing between help
usage and error message; second, cli.Ui methods are not concurrent safe.
Here, we introduce a custom error writer that buffers result and calls
ui.Error() in the write method and in the same goroutine.
For context, we need to wrap ui.Error because it's line-oriented, while
flags library expects a io.Writer which is bytes oriented.
Adds Windows targets to the client/allocs metrics tests. Removes the
`allocstats` test, which covers less than these tests and is now
redundant.
Adds a firewall rule to our Windows instances so that the prometheus
server can scrape the Nomad HTTP API for metrics.
