chore: makes instance-status works along with Moleculer lifecyle

[ricardogarim]

Proposed changes (including videos or screenshots)

This PR removes the use of MongoDB Change Streams on instance-status package. The removal of Change Stream items is part of an initiative started earlier this year, but resources related to instance-status were still pending.

instance-status is responsible for ensuring the connection and heartbeat between instances in a multi-instance monolithic Rocket.Chat deployment.

Since the Moleculer framework is already in use, we moved the lifecycle management of connections to it, such as node initialization, listing, etc.

As a result, it is no longer necessary to ping MongoDB and wait for a Change Stream notification to interpret a given node as valid.

The same timeout and heartbeat interval rules have been added to Moleculer:

• heartbeatInterval: process.env.MULTIPLE_INSTANCES_PING_INTERVAL || 10
• heartbeatTimeout: process.env.MULTIPLE_INSTANCES_EXPIRE || Math.ceil((defaultPingInterval * 3) / 60) * 60

Issue(s)

• ARCH-1392

Steps to test or reproduce

To validate these changes, you will need to run a multi-instance monolithic Rocket.Chat deployment.

Navigate to the apps/meteor directory and run the following command to start the first instance:

cd apps/meteor
TEST_MODE=true CI=true DISABLE_DB_WATCHERS=true meteor

Navigate to the build directory and execute the following:

cd ./apps/meteor/.meteor/local/build
cd .. && cd build && MONGO_URL=mongodb://localhost:3001/meteor INSTANCE_IP=localhost ROOT_URL=http://localhost:3000 PORT=3030 TEST_MODE=true DB_WATCHERS_DISABLED=true node main.js

This setup runs multi-instance communication using the TCP transporter. If you prefer to use NATS, you’ll need to include the NATS_TRANSPORTER environment variable. However, the changes primarily affect TCP connections.
