Link fixing should update Bitbucket URLs in Jira after migration of Bitbucket and Jira to Cloud

Summary

After migrating both Jira and Bitbucket to Cloud, adjustments to content are required to ensure the Bitbucket URLs are valid
http://bitbucket.company.com/projects/DEV/repos/Zontrax/browse/symphony/com/jigsy/Tresom/IngestionEngine/ConvertClass.java

These URLs may be contained in Jira issue descriptions, comments or custom field values.

http://bitbucket.company.com/projects/DEV/repos/Zontrax/browse/symphony/com/jigsy/Tresom/IngestionEngine/ConvertClass.java
http://bitbucket.company.com/projects/STACK/repos/Tempsoft/pull-requests/259/overview
http://bitbucket.company.com/projects/SPACEZ/repos/Andalax/commits/9562015

Please provide a method to fix links of these formats post-migration.

Please note that this is not related to the Jira development panel. This can be solved with Connect Jira Cloud to Bitbucket.
