* MM-23935 extend session expiry on user activity
- if user types anything before a session expires the session will be extended to now + session length
- ensures new session expiries are not written to DB too frequently
- new session store func for updating session ExpiresAt
- session length defaults for mobile and web/ldap changed from 180 days to 30 days
* Fixing system messages about non-visible users
* Adding unit tests to verify the new behavior
* Regenerating app layers

We invert the skipSend condition and outdent the remaining block
to make the code a bit more idiomatic.
While here, we also change the dropping message level from info to
warn because that's what it should be.
On user activity, we were clearing the job.pendingNotifications map.
But we had already created a copy of the notifications slice while
iterating the map. Therefore, if we pass the copied slice, it would
still have the old notifications which were originally deleted.
The unit tests would not catch this because it was testing the
job.pendingNotifications map and not actually checking if the email
handler was being called or not. We fix that now.

* MM-23800: remove goroutineID and stack printing
Each hub has a goroutineID which is calculated with a known hack.
The FAQ clearly explains why goroutines don't have an id:
https://golang.org/doc/faq#no_goroutine_id.
We only added that because sometimes the hub would be deadlocked and
having the goroutineID would be useful when getting the stack trace.
This is also problematic in stress tests because the hubs would
frequently get overloaded and the logs would unnecessarily have stack traces.
But that was in the past, and we have done extensive testing with
load tests and fuzz testing to smooth any rough edges remaining.
Including adding additional metrics for hub buffer size.
Monitoring the metrics is a better way to approach this problem.
Therefore, we remove these kludges from the code.
* Also remove deadlock checking code
There is no need for that anymore since
we are getting rid of the stack printing anyways.
Let's do a wholesale refactor and clean up the codebase.
* MM-23805: Refactor web_hub
This is a beginning of the refactoring of the websocket code.
To start off with, we unexport some methods and constants which did not
need to be exported. There are more remaining but some are out of scope for this PR.
The main chunk of refactor is to unexport the webconn send channel
which was the main cause of panics. Since we were directly sending
to the connection from various parts of the codebase, it would be possible
that the send channel would be closed and we could still send a message.
This would crash the server.
To fix this, we refactor the code to centralize all sending from the main
hub goroutine. This means we can leverage the connections map to check
if the connection exists or not, and only then send the message.
We also move the cluster calls to cluster.go.
* bring back cluster code inside hub
* Incorporate review comments
* Address review comments
* rename index
* MM-23807: Refactor web_conn
- Unexport some struct fields and constants which are not necessary
to be accessed from outside the package. This will help us moving
the entire websocket handling code to a separate package later.
- Change some empty string checks to check for empty string rather
than doing a len check which is more idiomatic. Both of them compile
to the same code. So it doesn't make a difference performance-wise.
- Remove redundant ToJson calls to get the length.
- Incorporate review comments
- Unexport some more methods
* Fix field name
* Run make app-layers
* Add note on hub check
The current code path for `CreatePostAsUser` tries to update the `LastViewedAt` for bots, which logs a warning message if the bot isn't actually in the channel.
This pull request changes the semantics of bot posting to not update the bot's `LastViewedAt` timestamp, avoiding this log altogether. It matches the semantics of `from_webhook`, but notably makes bots slightly less like users in that they no longer "read" channels when they post. This seems reasonable, but I'm both looking for validation of this semantic change in addition to the code review.

* MM-22044: Fix panic on web_conn send hello
(*Hub).Start is the central place for sending all web connection
related traffic. However, there was this one call to (*WebConn).Hello
which tried to send a message to a webconn separately.
This was a rare case, but it did occur under stress conditions generated
from a load test.
When the websocket send SEND_QUEUE_SIZE would get filled up and we would
attempt to make a broadcast, the non-blocking send would close the Send
channel of the web connection. During that time, if a web connection
would try to perform a broadcast, it would try to send to a closed channel
and cause a panic.
The solution is to bring back the sending of hello into the same goroutine
inside (*Hub).Start so that all state is centralised and we avoid
sending to a closed channel by sending the hello message inside the registering
code itself.
* Adding non-blocking send
* Simplify things
* Remove test
* Bring sendHello back
* Improve code further

Before this, for every single request we would create a new http.Client
from scratch. This was costly because every new client has internal
TCP connections which it reuses.
Therefore, originally, beyond a throughput of 800-1200 rps with a
concurrency of 50, beyond which it would run out of file descriptors.
Now it can support upto 8000-10000 rps.
An improvement by a factor of 10.
