feat(dashmate): import existing Core data

[shumkov]

Issue being fixed or feature implemented

Currently, most evo masternode owners run an evo masternode using only Core. We need a convenient method to import existing data and configuration so they don't need to sync and configure the node from scratch.

What was done?

• Added a step to import Core data to dashmate setup for already registered masternodes.

How Has This Been Tested?

Running dashmate setup locally
