instead of AsyncHBase.

Some browsers (aka firefox) like to encode { and } as %7B and %7D.  This
causes problem when parsing the query string since its using { and } to
figure out the metric and tags.  Without this the UI thows an error like
the following:

Request failed: Bad Request: No such name for 'metrics': 'server.nic.usage.mbit%7Bhost=host1%7D'

MetaScanner extracts (salt_width + metric_width) bytes from tsuid
to metric uid, this triggers IllegalArgumentException in
UniqueId.getNameAsync(id), then MetaScanner.call() won't never
call result.callback(null), and result.joinUninterruptibly() in
MetaSync.run() never returns.

BTW, I checked all usages of Const.SALT_WIDTH() and fixed some
other similar wrong calculations.

Thanks for the bug fixes!

This line was added in ab276c8 and based on indentation is likely an accidental commit.  It causes continuous spamming in our logs after upgrade.  Changing log level to "debug" to quiet it down.

Fixed a bug in which global_annotations were ignored by
GraphHandler.java (and thus, were not rendered by gnuplot). Added async
call to hbase to retrieve global annotations when required in a similar
fashion as that of QueryRpc.java.

Note: Since both GraphHandler.java and QueryRpc.java implement (similar)
query-processing logic, all of this should be unified in the future
(requires a large refactor to split all query logic with visualization
logic).
