Title: add options remove_prefix/add_prefix and its tests

'add_prefix' option is useful to route events flexibly, and to simplify configurations.
To build pipeline-like flow (like below), 'remove_prefix' is also needed.

type any_input_plugin
add_prefix original

type exec_filter
command foo_command_1
remove_prefix original
add_prefix converted_once

type exec_filter
command foo_command_2
remove_prefix converted_once
add_prefix fully_converted

type any_output_plugin
remove_prefix fully_converted
