Review and improve secrets env command design

[tegefaulkes]

Specification

The functionality of the secrets env command needs to be evaluated. The current implementation doesn't quite match some people intuitive understanding along with some potential features being missing. We need to have a discussion on what should be included and how. What exactly is missing and what can be changed.

During a meeting we discussed how the directories and naming of the secrets would work. Currently selecting a directory, every secret within that directories tree is included in the output with the same name as the secret name. If there is a conflict the behaviour is decided by a CLI option.

It has been suggested that to avoid conflicts we append the directories name to the secret so dir1/secret1 would become dir1_secret1 variable name. If the dir was selected directly then it would just be secret1. We could change this behaviour with a flag. This needs further discussion and spec.
