Pekka Enberg c4d8d7087e APIClient: Make API server errors human readable 
Make the error messages returned by Scylla API server human readable
from 'nodetool'.

For example, if an API URL is missing, print out the following error:

  [penberg@nero scylla-tools-java]$ ./bin/nodetool getcompactionthreshold ks test4
  nodetool: Scylla API server HTTP GET to URL 'column_family/minimum_compaction/ks:test4' failed: Not found
  See 'nodetool help' or 'nodetool help <command>'.

instead of the scary-looking error that we now print:

  [penberg@nero scylla-tools-java]$ ./bin/nodetool getcompactionthreshold ks test4
  error: Not found
  -- StackTrace --
