Update the releasescript to ensure that a distribution has been started
before starting it again. This functionality was accidentally removed
during the updates for gh-21474.
See gh-21474
Previously, as soon as the distribution of a release from Artifactory
to Bintray had been initiated we would start checking if it was
complete. This created a race condition between the distribution being
created and us checking if it was complete. If the check won the race
and happened before the creation, Bintray would respond with a 404.
This commit updates BintrayService to wait for up to 5 minutes for the
distribution to be created on Bintray. Once it has been created we
then wait for up to 40 minutes for it to be complete as we did before.
The use of Awaitility has been introduced in this commit to simplify
the logic required to wait for the distribution's creation and
completion.
Closes gh-18902
