Issue #206 -ec2 check to support IMDSv1 and IMDSv2 + moving env vars to conf file

[orensharoni]

we added support of IMDSv2 to the EC2 check with a fall back to IMDSv1,
also, some nginx env declarations were moved from the environment file to the nginx.conf file

Thank you for your contribution, @orensharoni - have been able to verify that this fixes your issue from #206 ?

I'll stand up an ec2 env and give it a check too.

yes, I used it on my dev setup and the ec2 test and deployment work,
the access_key and access_token should be also verified if posible

Excellent, thank you for confirming. I'll do a quick check on my end and then merge

Thanks again for your contribution. I tested these changes with the token approach and was able to verify it works well.

If you can correct the two typoes I highlighted we can go ahead and merge.

Thank you again for your contribution! Also special thanks to @HighOnMikey
for noticing the wrong file path in the env var inclusion portion
