This PR removes enforcement that the Vault token role disallows orphaned
tokens and recommends orphaned tokens to simplify the
bootstrapping/upgrading of Nomad clusters. The requirement that Nomad's
Vault token never expire and be shared by all instances of Nomad servers
is not operationally friendly.
Added a little more explanation about the why for creating the nomad service token with `-orphan` to recusce confusion about the orphan=false in the policy right above the example.
Caught some typos. Made units separate from the numbers 1GHz -> 1 GHz
after talking to Nick about questions of style (this has the side effect of making future spell checking easier).
- add `-L` to follow redirect when downloading example config files (file is linked to root, but gets redirected to _www_).
- fix role name to match recommendation
I apologize in advance for the rather long PR, but unfortunately there
is not an easy way to break this up into smaller chunks. This separates
the agent configuration into smaller, more consumable pieces just like
the job specification.
