Allow to split objectName to set envvar name

[emanuelflp]

Actually, we only have the possibility to use the full name of the parameter to set the variable name and optionally define a separator when using / in parameter name.

The suggestion consists in allow to split part of parameter name and use result to create the variable name.

Eg:

• basename - anything after the last '/' is the variable name (e.g. with path /service, parameter /service/app/param becomes PARAM)
• relative - anything after the path is the variable name (e.g. with path /service, parameter /service/app/param becomes APP_PARAM)
• absolute - the full path with parameter name is the variable name (e.g. with path /service, parameter /service/app/param becomes SERVICE_APP_PARAM)
