    Introduce sections in parameters file

    1. Currently parameters are treated as a flat list.
       With this change, parameters are organized in sections.
       parameters file example:
       user_params:
         key1: value1
         key2: value2
       custom_params:
         key3: value3
       solum_params:
         key4: value4

    2. Get parameters from app raw_content column
