🚀 Feature: Allow to capture shutdown event to make db integrations possible

[nev-21]

🔖 Feature description

I'm connecting to an external database using a dunction, just to make an integration (not to bypass appwrite).

When the container (that is executing a function) is turned off, allow to capture the graceful shutdown, maybe via SIGTERM, to execute an async method that will destroy the db connections. I tried with process.on('SIGTERM', async () => .....) but it doesn't work.

🎤 Pitch

There are many use cases that needs integrations (sometimes a direct connection to an external db is better to make an api) but It is necessary to close the connections when the container turns off (to avoid db connection leaks).

Maybe, adding a shutdown function to the primary function.
For example for the JS starter version.

const sdk = require('node-appwrite');

module.exports = async function(req, res) {
  const client = new sdk.Client();

  /* rest of starter code */

  res.json({
    areDevelopersAwesome: true
  });
};

module.exports.shutdown = async function(req, res) {
  const client = new sdk.Client();

  /* 
   * Run any shutdown logic code.
   * 
   * This function will execute only when the container is about
   * to get destroyed.
   */
  
};
