chore(dapi)!: disable unnecessary for v1 endpoints

[shumkov]

Issue being fixed or feature implemented

To ensure attack resistance for DAPI we need to disable endpoints what we don't need for Platfrom v1. In future versions these endpoints will be revisited to make sure that they are secure and enabled back.

What was done?

• Remove generateToAddress endpoint
• getBlock is marked as unimplemented
• getMasternodeStatus is marked as unimplemented

How Has This Been Tested?

None

Breaking Changes

getBlock and getMasternodeStatus maked as unimplemented for v1. It will be reconsidered in future versions
