APIClient: Fix error handling for POST if API call fails

Currently, we have a scary looking dtest failure when attempting to force flush a

  Nodetool command '/data/jenkins/workspace/scylla-1.3-dtest/label/monster/mode/release/smp/1/scylla/resources/cassandra/bin/nodetool -h localhost -p 7100 flush' failed; exit status: 2; stderr: Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF8

The problem is rather innocent: the API call fails and we leak
javax.ws.rs.ProcessingException, which is not available in nodetool's
classpath. In fact, we already fixed the problem for GETs in commit
02e0598 ("APIClient: Fix error handling if connection to API server
fails") so do the same thing for POSTs.
