Undesirable space in a metric "Unstoppable Jobs"

[Thierry Fournier]

Hi list,

Listing metrics for supervision, I see an undesirable space in a
metric name 54 "Unstoppable Jobs".

    44.CompressBpsRateLim.1:CLP:u32:0
    47.Tasks.1:MGP:u32:455
    48.Run_queue.1:MGP:u32:1
    49.Idle_pct.1:MaP:u32:92
    50.node.1:COS:str:ozon3
    52.Stopping.1:MGP:u32:0
    53.Jobs.1:MGP:u32:81
 -> 54.Unstoppable Jobs.1:MGP:u32:0
    55.Listeners.1:MGP:u32:31
    56.ActivePeers.1:MGP:u32:0
    57.ConnectedPeers.1:MGP:u32:0
    58.DroppedLogs.1:MGP:u32:0
    59.BusyPolling.1:MGP:u32:0

This space is introduced two year ago. If anyone uses this variable
I suggest a rename with "_" in place of space.
