* MM-16479: panic on io.Copy error in test
I'm unable to reproduce the original report on MM-16479, but in a bid to help track down a potential failure in the future, I've added a panic on err returned from `io.Copy` within the plugin, as this seems like the only path on which the hook could return successfully but fail to show the updated contents.

- The tests now fully buffer the data vefore uploading it. The prior
code was much more complex because it was intended to eventually
mature into generic client code; not a priority, definitely not
valuable for this test.
- Also improved error handling in TestHookFileWillBeUploaded for

* [MM-13828] Running tests from a new temp folder with all test resources
Possible fix for #10132
All packages which have a TestMain and use testlib.MainHelper will have a new current working directory which will have all the test
resources copied.
Note: default.json is copied as config.json as well to make sure tests don't have any impact due to changes in config by devs
* [MM-13828] Added TestMain to remaining packages to use testlib.MainHelper
This makes sure tests from all packages run with same test resources, setup in a new temp folder for each package
* Updated Jenkins file to not not config/default.json
This makes sure CI has same config files as a dev's machine

* MM-10856: deduplicate posts with the same pending post id
Leverage a fixed size cache with a window of 30 seconds to deduplicate posts received by a single app server. Clients that duplicate the same pending post id will see one request potentially delayed until the first finishes, after which the same payload should be returned by both. Duplicate posts outside the 30 second window will not be de-duplicated.
Note that the cache is not synchronized between app servers. In an HA cluster consisting of more than one app server, sticky load balancing (e.g. hashing by IP or Session ID) is required to route the users to the same app instance for multiple requests.
Other options considered for this feature:
* adding a column to the `Posts` table: rejected as being too heavyweight
* maintaining a `PendingPostIds` table: similarly rejected for the database impact
* using the pending post id as the post id and relying on the unique constraints on the Post table: rejected for being difficult to show that it's safe to use a client-provided value as the row identifier
* utils/lru: simplify to ttl internally and for new methods
* move seenPendingPostIdsCache to App.Server
* just fail concurrent post requests, vs. trying to wait
* add debug log when create post is deduplicated
* guard app plugins with mutex
Shutting down the app could race with a goroutine that uses the plugins environment, since we shut down the plugins first before cleaning up goroutines.

* ensure plugin is always shutdown
Once we call `.client.Client()` the plugin has started, and must be shut
down. `newSupervisor` sometimes returned with an error (and without a
reference to the supervisor), leaving the client running indefinitely.
* Clarify the documentation to explain that plugin hooks will not trigger until `OnActivate` returns successfully, and will stop triggering just before `OnDeactivate` is called.
* test for plugin deadlock
* plugin/environment.go: switch to sync.Map
From: https://golang.org/pkg/sync/#Map
> If a goroutine holds a RWMutex for reading and another goroutine might call Lock, no goroutine should expect to be able to acquire a read lock until the initial read lock is released. In particular, this prohibits recursive read locking. This is to ensure that the lock eventually becomes available; a blocked Lock call excludes new readers from acquiring the lock.
The previous `RWMutex` was not safe given that we effectively acquired read locks recursively (hook -> api -> hook). This worked up until we activated or deactivated plugins, tried to acquire a write lock, and the plugin used the API to effectively trigger another hook.
Switching to sync.Map avoids this by divesting the need to lock at all, avoiding the potential for a recursive lock in the first place.
