fatal error: MSpanList_Insert

[josh-padnick]

When running the ec2-snapper binary on macOS High Sierra, I received the following output:

failed MSpanList_Insert 0xb9e000 0x88223d97ee77 0x0 0x0
fatal error: MSpanList_Insert

I recall several issues with running programs binaries compiled by Go on MacOS High Sierra until Go released an update. I'm assuming we can resolve this by just re-compiling the program with a later version of Go. This involves an update to the circle.yml to run some of the latest Gruntwork tooling for installing Go.

We should also replace glide with go dep.
