feat(service): automate csv assignment inside enclave.json

[qascade]

Description

CSVs can't be moved inside enclaves unless explicitly mentioned inside the enclave.json. Check files field in service/temp_enclave.json. I want that to be automated and to be picked from Yaml, not through temporary CSV's. The enclave.json is to created/modified before ego-sign using sources specified in yaml.

How are you planning to resolve this issue?

One of the following strategies may be used. You are free to create you own strategy as well.

1. Use basic json Writers to manipulate the file.
2. Use some templates and use pongo2 templating engine.
