Blake Covarrubias 9260711c82 docs: Update responses for /v1/session/ endpoints post 1.7 
Update output for /v1/session/ endpoints to match output post Consul
1.7.0.

Documents new `NodeChecks` and `ServiceChecks` parameters which were
added in that release.

Resolves #7341, resolves #10095

Freddy 7d48383041
Avoid panic on concurrent writes to cached service config map (#10647) 
If multiple instances of a service are co-located on the same node then
their proxies will all share a cache entry for their resolved service
configuration. This is because the cache key contains the name of the
watched service but does not take into account the ID of the watching
proxies.

This means that there will be multiple agent service manager watches
that can wake up on the same cache update. These watchers then
concurrently modify the value in the cache when merging the resolved
config into the local proxy definitions.

To avoid this concurrent map write we will only delete the key from
opaque config in the local proxy definition after the merge, rather
than from the cached value before the merge.

Blake Covarrubias 441a6c9969
Add DNS recursor strategy option (#10611) 
This change adds a new `dns_config.recursor_strategy` option which
controls how Consul queries DNS resolvers listed in the `recursors`
config option. The supported options are `sequential` (default), and
`random`.

Closes #8807

test helper behaves closer to production.

ui: [BUGFIX] Ensure we use the ns query param name when requesting permissions (#10608) 
Previously when namespaces were enabled, we weren't requesting permission for the actively selected namespace, and instead always checking the permissions for the default namespace.

This commit ensures we request permissions for the actively selected namespace.

Daniel Nephin ff26294d63 consul: fix data race in leader CA tests 
Some global variables are patched to shorter values in these tests. But the goroutines that read
them can outlive the test because nothing waited for them to exit.

This commit adds a Wait() method to the routine manager, so that tests can wait for the goroutines
to exit. This prevents the data race because the 'reset to original value' can happen
after all other goroutines have stopped.
