The keys of `meta` fields have all characters outside of `[A-Za-z0-9_.]`
replaced by underscores when we create `NOMAD_META` environment variables. Make
sure this replacement is documented.

Although most of the time jobs will be assigned to a single node pool, users may
want to set the node pool to "all" and then constraint to a subset of node
pools. Add support for setting a contraint like `${node.pool}`.
* fingerprint: add node attr for reserverable cores
Add an attribute for the number of reservable CPU cores as they may
differ from the existing `cpu.numcores` due to client configuration or
OS support.
Hopefully clarifies some confusion in #14676
* add changelog
* num_reservable_cores -> reservablecores
Closes#12927Closes#12958
This PR updates the version of redis used in our examples from 3.2 to 7.
The old version is very not supported anymore, and we should be setting
a good example by using a supported version.
The long-form example job is now fixed so that the service stanza uses
nomad as the service discovery provider, and so now the job runs without
a requirement of having Consul running and configured.
Follow up to memory oversubscription - expose an env-var to indicate when memory oversubscription is enabled and what the limit is.
This will be helpful for setting hints to app for memory management.
