Node-v8 LTS support end on 2019-12-31 to meet EOSL of openssl-1.0.2

[shigeki]

According to the support policy of openssl-1.0.2, Node-v8 LTS support end is 2019-12-31 that is about 3 months earlier than our plan if we continue to use openssl-1.0.2.
See nodejs/node#11828.

This seems like a reasonable deviation, and its good if we document from the outset of Node version 8 so there should be no surprises later on.

@nodejs/lts can one of you add the lts-agenda label to this?

[jasnell]

This is unfortunate but likely necessary. Fortunately it will not impact the scheduling of the active LTS period. I will get this updated in the schedule

[gibfahn]

It sounds to me like we're going to default to this assuming there are no objections (and #133 already updated the schedule to reflect this).

[gibfahn]

There were no objections in the meeting, so this is decided.
