operation index for target also

[kfangw]

Github Issue

#680

Background

Current /accounts/{id}/operations API returns operations which are sent by source only
The client such as wallet and Explorer requires that the API returns operations which are related not only source but also the target.

Solution

• Add target index for block operation

• Add peers index for block operation

• query operations for peers index

Possible Drawbacks

[kfangw]

when I added testcases, description will be filled, and I will request the review.

[kfangw]

This PR depends on #765 and #766.
Hence, this will be resumed when those are merged.

Can you rebase from #765 ? This PR is merged from #765. I think that It merged after #765 is merged.
What do you think this and that (#765) ? @kfangw @spikeekips @Charleslee522 @Geod24

[kfangw]

I rebased it on master not #765
Could you review again? @anarcher

[anarcher]

LGTM!
