[FEATURE] Move types to separate files to avoid circular dependencies

[filmakarov]

Feature or Improvement Description

Move types to separate files to avoid circular dependencies

Benefits & Outcomes

SDK becomes complex and sometimes files inherit types from each other.
Maybe it can make sense to switch from co-location of types and implementations, to have separate types files per module/service
