EW-1057: Barrel Exports changes and Deep imports modified

[HKayed]

Description

In the Dataport TSP code review, the TSP related code were reviewed. In this ticket the TODOs related to imports and barrel files have to be solved. The to-dos include the following:

Explicit export in barrel files (no '*' exports)
No deep module imports if possible (maybe export necassary things from modules - if you are unsure, ask Thomas or Cedric)
Delete 'src' from module imports if it is possible

Changes are done in this scope

TSP (so ungefähr):
infra/tsp-client
infra/sync
modules/provisioning/strategy/tsp
