Fix Telegraf Env Handling issue

[suyadav1]

This PR contains following changes:

• Telegraf version >=1.38.0 makes the strict environment variable handling the default: https://docs.influxdata.com/telegraf/v1/release-notes/#v1380. To keep the existing behavior as it is, run Telegraf using --non-strict-env-handling flag.
• Zlib gem installation is failing intermittently for Arm64 as it depends on zlib-devel header files.
