Blackfire profiling cli with --env

[manuelson]

When you launch the command warden blackfire run {command} blackfire gives you the option to add the --env parameter.

Warden should support a new global variable on .env file (e.g. BLACKFIRE_ENV_ID) by editing the .cmd commands/blackfire.cmd it should accept the --env parameter as documented by blackfire (https://blackfire.io/docs/profiling-cookbooks/profiling-cli)

This looks like a very straightforward feature to add. I've created an issue for your feature request #699
