split snapshotter

[Alenar]

Content

This PR makes the snapshotter code more manageable by:

• moving it to services so it's no longer uncategorized at the source route
• split the module into several files to limit amount of code to navigate and make it more cohesive.

This PR also simplify local uploaders constructors by removing their StdResult (no longer needed since #2241)
