This eases adoption of the jobspec package by other projects (e.g. terraform nomad provider, Lavant). Either by consuming directy as a library (hopefully without having go mod import rest of nomad) or by copying the package without modification.
Ideally, this package will be published as an independent module. We aren't ready for that considering we'll be switching to HCLv2 "soon", but eitherway, this seems like a reasonable intermediate step if we choose to.
This change provides an initial pass at setting up the configuration necessary to
enable use of Connect with Consul ACLs. Operators will be able to pass in a Consul
Token through `-consul-token` or `$CONSUL_TOKEN` in the `job run` and `job revert`
commands (similar to Vault tokens).
These values are not actually used yet in this changeset.
* jobspec: breakup parse.go into smaller files
* add sidecar_task parsing to jobspec and api
* jobspec: combine service parsing logic for task and group service stanzas
* api: use slice of ConsulUpstream values instead of pointers
