Tweak wording in changelog to match other entries.

docs: add more detail to connect stanzas

When multiple developers are working on e2e testing, it helps to be
able to identify which infrastructure belongs to which Nomad SHA and
which developer. This adds tags to the EC2 instances.

e2e: script check testing

docs: Add host volume acl docs

acl_docs: Stylistic improvements

Fix host volume path

Fix inplace updates bug with group level networks

During inplace updates, we should be using network information
from the previous allocation being updated.

This semi-reverts #6275, as the tests are intermittently
failing in CI.

Initial placeholder connect docs

connect: check if consul is on PATH

These are the tests skipped in #6271.

Only in -dev-connect mode for now since its valid to install Consul
after Nomad has started in production.

I put this property in the wrong place. 

I’ve found how to fix the mock API in the tests but
they’re failing to pass with headless Chrome only,
so they’re skipped for now.
