binman: Allow for logging information to be displayed
Binman generally operates silently but in some cases it is useful to see
what Binman is actually doing at each step. Enable some logging output
with different logging levels selectable via the -v flag.

+Logging
+-------
+
+Binman normally operates silently unless there is an error, in which case it
+just displays the error. The -D/--debug option can be used to create a full
+backtrace when errors occur.
+
+Internally binman logs some output while it is running. This can be displayed
+by increasing the -v/--verbosity from the default of 1:
+
+ 0: silent
+ 1: warnings only
+ 2: notices (important messages)
+ 3: info about major operations
+ 4: detailed information about each operation
+ 5: debug (all output)
