Bash script exports JSON object as an environment value

[farshidtz]

The Bash implementation of the program doesn't perform validation for value types. It queries the top level keys (env.<key> and apps.<app>.env.<key>) and expects the value to be of primitive types. However, the user may have set a nested key or a JSON object as the value. In such case, the program exports a stripped down JSON object as the environment value.

For example, setting:

• env.x.y=value, exports X=y:value
• env.a.b.c=value, export A=b:c:value
• env.k={"j":"value"}, exports K=j:value
