Fix heartbeat monitor to properly set peer type

[sstanculeanu]

Description of the reasoning behind the pull request (what feature was missing / how the problem was manifesting itself / what was the motive behind the refactoring)

• heartbeat v2 only responds with validator/observer as peer type on /node/heartbeatstatus

Proposed Changes

• integrate peerTypeProvider into heartbeat v2 monitor in order to properly compute the peer type

Testing procedure

• system test + proxy call to /node/heartbeatstatus after epoch 3(when heartbeat v1 is disabled) in order to check if eligible/waiting is displayed for validators
