Setup and check honeycomb on all DUTs
- methods implementing HTTP requests (PUT,GET,POST,DELETE) - methods for parsing HTTP responses - methods for honeycomb setup on DUT - updated constants.py - keywords for honeycomb setup and communication - simple honeycomb sanity test (not enabled for jenkins job runs) Change-Id: I589f0ca56cc01072b92fe9363aed16a4098aee40 Signed-off-by: selias <samuel.elias@pantheon.tech>
