cli/command/formatter: add TrunateID utility
We were depending on pkg/stringid to truncate IDs for presentation. While
traditionally, we used a fixed length for "truncated" IDs, this is not
a strict requirement (any ID-prefix should work, but conflicts may
happen on shorter IDs).
This patch adds a local
TruncateID()
utility in the formatter package;it's currently using the same implementation and length as the
stringid.TruncateID
function, but may diverge in future.remove uses of pkg/stringid.GenerateRandomID()
This utility was only used for testing, and to generate a random
suffix for Dockerfiles. As we don't need the same contract as
pkg/stringid.GenerateRandomID() (not allow all-numeric IDs as they
would not be usable for hostnames), we can use a local test-utility,
and local implementation for the random suffix instead.
