Redirect streams to /dev/null unless verbose enabled

Redirect stdout and stderr to /dev/null unless the verbose option
is specified. This is a usability enhancement for the majority
use case which is a daemon-like mode for logshifter in which no
output should ever be expected from the program. If the streams
are left open and undirected, readers may block waiting for
output from logshifter itself.

Moved pruning of non-districted/non-zone nodes(when districted/zone nodes are available) from rpc_find_all_available to select_best_fit_node.
Rationale: Node selection plugin should have flexibility to choose any candidate node from non-districted/districted/non-zone/zone nodes.
