Our store upgrade methods used mlog.Critical and then slept
for a second and triggered os.Exit.
First of all, with the new mlog refactor Critical wasn't a standard
log level so it was never to be logged.
And secondly, this completely missed the fact that there already
existed an API method Fatal which did exactly this.
We mark the Critical API as deprecated, and use Fatal for all
occurences.
The choice should be between either to use Error or Fatal.
While here, we also remove the non-standard exit codes which
just confused things further while debugging.

* Added a sqlXPassThrough layer
This layer embeds the original sqlx object and wraps some
key methods to avoid some boilerplate.
- Add timeout to all methods from the timeout in settings.
- Added trace functionality.
- Added auto-rebind capabilities so that each store method
doesn't need to call rebind every time.
- Added auto-lowering of query string to support NamedExec
for both MySQL and Postgres
All methods are not wrapped as all are likely not to be called
from our code. As and when they are called, support will be added.

* Prepare support for sqlx
Just setting up some basic skeleton to start
replacing gorp queries with sqlx.
There is still an issue with efficiently writing
cross-platform named queries, because :FieldName
needs to be :fieldname for Postgres.
The positional params can be rebound depending on
driver name. But named queries can't from my
investigation. Will look into this.

* MM-35030: Hoist GetDBVersion before creating store
The creation of the store included running the migrations
which means that SQL statements would be executed before
we could make the check for DB version.
We perform the DB check before running the migrations.

Remote Cluster Service
- provides ability for multiple Mattermost cluster instances to create a trusted connection with each other and exchange messages
- trusted connections are managed via slash commands (for now)
- facilitates features requiring inter-cluster communication, such as Shared Channels
Shared Channels Service
- provides ability to shared channels between one or more Mattermost cluster instances (using trusted connection)
- sharing/unsharing of channels is managed via slash commands (for now)
* MM-33818: Add replica lag metric
We add two new metrics for monitoring replica lag:
- Monitor absolute lag based on binlog distance/transaction queue length.
- Monitor time taken for the replica to catch up.
To achieve this, we add a config setting to run a user defined SQL query
on the database.
We need to specify a separate datasource field as part of the config because
in some databases, querying the replica lag value requires elevated credentials
which are not needed for usual running of the application, and can even be a security risk.
Arguably, a peculiar part of the design is the requirement of the query output to be in a (node, value)
format. But since from the application, the SQL query is a black box and the user can set any query
they want, we cannot, in any way templatize this.
And as an extra note, freno also does it in a similar way.
The last bit is because we need to have a separate datasources, now we consume one extra connection
rather than sharing it with the pool. This is an unfortunate result of the design, and while one extra
connection doesn't make much of a difference in a single-tenant scenario. It does make so, in a multi-tenant scenario.
But in a multi-tenant scenario, the expectation would already be to use a connection pool. So this
is not a big concern.
https://mattermost.atlassian.net/browse/MM-33818
```release-note
Two new gauge metrics were added:
mattermost_db_replica_lag_abs and mattermost_db_replica_lag_time, both
containing a label of "node", signifying which db host is the metric from.
These metrics signify the replica lag in absolute terms and in the time dimension
capturing the whole picture of replica lag.
To use these metrics, a separate config section ReplicaLagSettings was added
under SqlSettings. This is an array of maps which contain three keys: DataSource,
QueryAbsoluteLag, and QueryTimeLag. Each map entry is for a single replica instance.
DataSource contains the DB credentials to connect to the replica instance.
QueryAbsoluteLag is a plain SQL query that must return a single row of which the first column
must be the node value of the Prometheus metric, and the second column must be the value of the lag.
QueryTimeLag is the same as above, but used to measure the time lag.
As an example, for AWS Aurora instances, the QueryAbsoluteLag can be:
select server_id, highest_lsn_rcvd-durable_lsn as bindiff from aurora_global_db_instance_status() where server_id=<>
and QueryTimeLag can be:
select server_id, visibility_lag_in_msec from aurora_global_db_instance_status() where server_id=<>
For MySQL Group Replication, the absolute lag can be measured from the number of pending transactions
in the applier queue:
select member_id, count_transaction_remote_in_applier_queue FROM performance_schema.replication_group_member_stats where member_id=<>
Overall, what query to choose is left to the administrator, and depending on the database and need, an appropriate
query can be chosen.

* MM-31356: Add a minimum required version check for Postgres
To keep conformance with our failing fast and obvious philosophy,
we add a check to prevent Mattermost server from starting
if the postgres version is below 10.0.
This gives customers a chance to upgrade their database before upgrading
their Mattermost version, than to run into weird compatibility issues
after they have finished the upgrade.
