added extraEnv, envFrom to statefulset template

[shucle-devops]

Description

• There was no way to inject env var like TZ to presto container on presto's helm chart.
• I added extraEnv, envFrom to presto helm template, and initialized those values with empty array.
• It works fine and users will be able to use custom env vars from presto containers.
