Add enpoint to get node information

[CruiseMan]

Currently ( at least i did no found) no way to get node information. How i can tell what version of thor i run over REST ?

@qianbin Can you advise here ?

You are right. There's no way to get node version. However, the version of REST API can be found in the field X-Thorest-Ver of response headers.

curl -I  http://localhost:8669/blocks/best
