Update the matrix row to have deployed version details

[Saup21]

The matrix row has deployed environments data named as environment node, which is derived from deployed_versions data. Now deployed version has the application instance details which cannot be represented under environment node because that can confuse customers to think we have application instance column in environments table or something. What we are planning to do is to rename the environment node to maybe something like deployed-environment and refactor the data inside it to contain deployed version data and embed environment data in it or have another node in the response to contain deployed_versions data to maintain backward compatiblily
