Adds nomad monitor command. Like consul monitor, this command allows you
to stream logs from a nomad agent in real time with a a specified log
level

Upgrade go-hclog to latest version
The current version of go-hclog pads log prefixes to equal lengths
so info becomes [INFO ] and debug becomes [DEBUG]. This breaks
hashicorp/logutils/level.go Check function. Upgrading to the latest
version removes this padding and fixes log filtering that uses logutils
Check
AgentMonitor is an endpoint to stream logs for a given agent. It allows
callers to pass in a supplied log level, which may be different than the
agents config allowing for temporary debugging with lower log levels.
Pass in logWriter when setting up Agent
The Connect integration uses bridge networking and iptables to send
traffic between containers, but the RedHat family of Linux distros
sets some of the kernel tunables this requires to be optimized for VMs
rather than containers. We can document this behavior for now and
consider better operator feedback for pre-flight checking later.
makeAllocTaskServices did not do a nil check on AllocatedResources
which causes a panic when upgrading directly from 0.8 to 0.10. While
skipping 0.9 is not supported we intend to fix serious crashers caused
by such upgrades to prevent cluster outages.
I did a quick audit of the client package and everywhere else that
accesses AllocatedResources appears to be properly guarded by a nil
check.
When a job has a task group network, this log line ends up being
misleading if you're trying to debug networking issues. We really only
care about this when there's no port map set, in which case we get the
error returned anyways.
Fixes typo in word "failed".
Fixes bug where incorrect error is printed. The old code would only
ever print a nil error, instead of the validationErr which is being
created.
`admissionValidators` doesn't aggregate errors correctly, as it
aggregates errors in `errs` reference yet it always returns the nil
`err`.
Here, we avoid shadowing `err`, and move variable declarations to where
they are used.
`groupConnectHook` assumes that Networks is a non-empty slice, but TG
hasn't been validated yet and validation may depend on mutation results.
As such, we do basic check here before dereferencing network slice
elements.
Vault 1.2.0 deprecated `period` field in favor of `token_period` in auth
role:
> * Token store roles use new, common token fields for the values
> that overlap with other auth backends. `period`, `explicit_max_ttl`, and
> `bound_cidrs` will continue to work, with priority being given to the
> `token_` prefixed versions of those parameters. They will also be returned
> when doing a read on the role if they were used to provide values initially;
> however, in Vault 1.4 if `period` or `explicit_max_ttl` is zero they will no
> longer be returned. (`explicit_max_ttl` was already not returned if empty.)

Ensure that we're reusing the base configuration between client and
servers without the possibility of drift. Reduce the amount of `sed`
mangling of the configuration file, and make recommended changes from
`shellcheck` for this section of the provisioning script.
Fixes some rebase errors on the Nomad config as well.
Share base configuration for telemetry and consul. Have the server
configurations respect the `var.server_count` config. Make changes
recommended by `shellcheck` in the provisioning scripts for this section.
Switch to OS/arch-tagged release bundles on S3 for compatibility with
adding Windows builds in the near future.
Match the configuration directory layout we're using for Consul and
other services. Make recommended changes from `shellcheck` for this
section of the provisioning script.
Update the Consul and Vault configs to take advantage of their
included `go-sockaddr` library for getting the IP addresses we need in
a portable way. This particularly avoids problems with "predictable"
interface names provided by systemd.
Also adds the `sockaddr` binary to the Packer build so we can use it
in our provisioning scripts.
