releasenotes: add similarity check function to compare incoming notes
It is possible that the incoming note fragments might have some similar content
as the existing release notes. In case of a bug fix, we match for issueNNNN in $
existing notes. For other general cases, it makes use of fuzzywuzzy library to
get a similarity score. If the score is above a certain threshold, we ignore
the fragment otherwise add it. But the score might be misleading for small comm$
messages. So, it uses similarity function if only the length of string (in word$
is above a certain number. The patch also adds tests related to its usage.
But it needs improvement in the sense of combining the incoming notes. We can
use interactive mode for adding the notes. Maybe we can do this if similarity
score is under a certain range.
