Add paging mechanism to /peer api endpoint

[H3npi]

Expected behaviour

when calling the Endpoint there should be a metadatalist which contains the following information: totalPeers: numberOfPeers: offset: data:

the totalPeers are the total number of peers in the peer.list numberOfPeers are the number of peers contained in the data object offset: how many peers are skipped. data: the actual peer objects

This would need a sorting at some point, i suggest data._id from the peer as a sorting indicator.

Actual behaviour

you get all the peers at once

Steps to reproduce

make a call to /peers

I would consider adding a full express app as api endpoint. More flexibility in the future. Also regarding the versioning.
