[Feature]: Split VsCode Extension features to dedicated modules

[kpanot]

Context

The VsCode extension is providing feature to simplify and accelerate the development of Otter Application. Today the VsCode application code inclus all the features provided by the extension. For the clarity of the code, it would make more sense to have the feature implementation in its dedicated module.

Proposal

Separate the code of the VsCode extension to the feature dedicated module.
