vlib: add a "vpplog" debug CLI
To add arbitrary text to the vlib log. Combines nicely with comment/uncomment and the macro expander: define MY_FEATURE uncomment # or comment ... $(MY_FEATURE) { vpplog { My feature was enabled } } Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: Ia019f0a8fa670d8593ae01595f5ef410796e5b1c
