Enable telemetry opt-out #254

[gardner]

Users can opt out of telemetry by setting the environment variable CREWAI_TELEMETRY_OPT_OUT

Fixes:

• Connection Timeout Error with telemetry.crewai.com #254
• turning off crew ai telemetry #241
• Can I disable anonymous telemetry ?  #372

This branch has been published to https://pypi.org/project/crewai-clean for testing.

As an software architect within a bank which has tons of firewall, such requests for enabling firewall will never get approved , without opting out feature, we will get errors in logs, and we will have a sub standard experience. Unfortunately for us, it would be a no go with crewai if we don't have an opt out of telemetry.

+1 on disabling telemetry for running in airgapped environments, any updates on this?

@joaomdmoura Can you have a look at this one, please?
Note in an enterprise environment this is a blocking point

PR Review 🔍

⏱️ Estimated effort to review [1-5]	2, because the PR is small and the changes are straightforward, but it requires careful consideration of the environment variable handling and its impact on the telemetry system.
🧪 Relevant tests	No
⚡ Possible issues	Possible Bug: The environment variable check os.environ.get("CREWAI_TELEMETRY_OPT_OUT", False) will not work as intended because os.environ.get will return a string and not a boolean. This could lead to the telemetry not being disabled even if the environment variable is set.
🔒 Security concerns	No

Code feedback:

relevant file	src/crewai/telemetry/telemetry.py
suggestion	Consider explicitly checking for a specific string value to determine if telemetry should be disabled. This ensures that setting the environment variable to any string will not unintentionally disable telemetry. For example, you could check if the environment variable is set to 'true' or '1'.
