The `kolide_launcher_info` should expose runtime.

[directionless]

I often want to see what the launcher runtime is. We should add that to the kolide_launcher_info table

Do we want a new column go_version set to runtime.Version() for this issue? Or something else?

[directionless]

Heh, I guess runtime is pretty ambiguous. I was thinking about uptime -- how old is this process.

But maybe there are good values from runtime that we should expose too.

(and yes, I think new columns)

Ah, I see we even already pull some of those runtime values in this table -- probably don't need to do anything other than the uptime here, then.

Proposed requirements for issue:

• On launcher startup, store the startup time (in the knapsack, or potentially in a new store like the OsqueryHistoryInstanceStore store if we think we might want to store history in the future)
• Modify the kolide_launcher_info table to add a new column, uptime, which should be the number of seconds since the launcher startup time

[directionless]

Sounds right. But....

• Not sure we need launcher_uptime_friendly
• The table is already launcher I'd call the column uptime no need to repeat it
