Manage application env from rebar3 profile

[Nyirő Gergő]

Dear list,

I would like to change some constant during testing e.g.: cycle time
of a periodic job.
It would be ideal to manage it from rebar3 config, but I don't see how
should I edit
the application env variables from rebar3 profiles. Is that even
possible? Should I use
persistent_term instead of application:get_env?

Thanks for your help in advance,
Gergő
