Log the time taken to harvest each repository

[cessda-bitbucket-importer]

Original report on BitBucket by Matthew Morris (GitHub: matthew-morris-cessda).

It would be useful to log the time taken for each repository to be harvested.

• To evaluate the performance of repositories, which can be used for feedback to SPs
• To understand the harvester run time

A new field, repository_duration, will be created in the logs.
