In the `entrypoint.sh` script, we check if the MongoDB in use, has
replicaSet initiated or not. This is usually done with a `rs.initiate()`
on the cluster.
We need the replicaSet to be enabled on MongoDB, since the backend
server relies on MongoDB `changeStream`s, which is a feature, only
available if replicaSet is enabled.
However, to use the `changeStream` APIs, having the `read` or
`readWrite` role on MongoDB is enough. But the check we do in
`entrypoint.sh`, runs `rs.status()` to see if `replicaSet` is initiated.
This `rs.status()` call, unfortunately, requires the `ClusterMonitor`
role, unlike the `changeStream` API.
To tackle this, we created the `appsmithctl check_replica_set` command.
This command would attempt to use the `changeStream` API, and report
success or failure. But this failed on certain configurations, where
MongoDB was running as a single-node-cluster, on localhost, or a
local/internal network. This was an edge case.
That edge case is solved by this PR. With this, we can use `appsmithctl
check-replica-set` in the `entrypoint.sh` again.

- Auto-cleanup of backup files using env variable APPSMITH_BACKUP_ARCHIVE_LIMIT (default value is 4) after every backup.
- Updated docker file to include watchtower hook scripts.
- Error mail interval to 6hrs.
## Description
This PR adds to the `estimate_billing` option to the `appsmithctl` command. This will help existing users estimate their bill when they consider upgrading to the paid edition.
Usage:
```
appsmithctl estimate_billing
Options:
--sessionPrice The price per active session. Defaults to 0.3
--priceCap The price cap for a user in a given month. Defaults to 15
```
A user can also run the command for various scenarios to determine the optimum capacity tier.
