REMINDER: F30 Code complete (testable) deadline in one week

[Ben Cotton]

According to the Fedora 30 schedule[1], the deadline for Changes to be
code complete (i.e. testable enough for beta) is Tuesday 19 February.
At this time, all Changes should be testable and tracker bugs should
be set to the MODIFIED state. For more information on this deadline,
see the wiki[2].
