We expect every Nomad API client to use a single connection to any
given agent, so take advantage of keep-alive by switching the default
transport to `DefaultPooledClient`. Provide a facility to close idle
connections for testing purposes.
Restores the previously reverted #12409

When a service is updated, the service hooks update a number of
internal fields which helps generate the new workload. This also
needs to update the namespace for the service provider. It is
possible for these to be different, and in the case of Nomad and
Consul running OSS, this is to be expected.
This change modifies the template task runner to utilise the
new consul-template which includes Nomad service lookup template
funcs.
In order to provide security and auth to consul-template, we use
a custom HTTP dialer which is passed to consul-template when
setting up the runner. This method follows Vault implementation.

The only difference is DefaultTransport sets DisableKeepAlives
This doesn't make much sense to me - every http connection from the
nomad client goes to the same NOMAD_ADDR so it's a great case for keep
alive. Except round robin DNS and anycast perhaps.
Consul does this already

Move some common Vault API data struct decoding out of the Vault client
so it can be reused in other situations.
Make Vault job validation its own function so it's easier to expand it.
Rename the `Job.VaultPolicies` method to just `Job.Vault` since it
returns the full Vault block, not just their policies.
Set `ChangeMode` on `Vault.Canonicalize`.
Add some missing tests.
Allows specifying an entity alias that will be used by Nomad when
deriving the task Vault token.
An entity alias assigns an indentity to a token, allowing better control
and management of Vault clients since all tokens with the same indentity
alias will now be considered the same client. This helps track Nomad
activity in Vault's audit logs and better control over Vault billing.
Add support for a new Nomad server configuration to define a default
entity alias to be used when deriving Vault tokens. This default value
will be used if the task doesn't have an entity alias defined.
When we unmount a volume we need to be able to recover from cases
where the plugin has been shutdown before the allocation that needs
it, so in #11892 we blocked shutting down the alloc runner hook. But
this blocks client shutdown if we're in the middle of unmounting. The
client won't be able to communicate with the plugin or send the
unpublish RPC anyways, so we should cancel the context and assume that
we'll resume the unmounting process when the client restarts.
For `-dev` mode we don't send the graceful `Shutdown()` method and
instead destroy all the allocations. In this case, we'll never be able
to communicate with the plugin but also never close the context we
need to prevent the hook from blocking. To fix this, move the retries
into their own goroutine that doesn't block the main `Postrun`.
