[JIra] Ticket with added attachment are not visible by Crucible

[Don-Touch]

There is an issue with jira.add_attachment() post method.
After adding attachment to some ticket through this method, the ticket disappeares in Atlassian Crusible.
I've found one discrepancy between adding attachment through curl command and the python method.
Curl request:
curl -D- -u user:password -H "X-Atlassian-Token: no-check" -F "file=@file.png" https://{jira_link}/rest/api/2/issue/{issue_key}/attachments.
In response I can see "mimeType":"image/png", where it's missing in response of jira.add_attachment().

The way to reproduce is to open attachment url in browser. Attachment added manually and through curl is opened as a picture in browser. Attachment added by method is being downloaded.

Hi!
Hm, interesting why through curl mimeType is matching well.

I have a hunch this is happening because we don't explicitly set the content_type of the file before making the request. I will try to do some testing to see if this is the case.

We may need to do something like this to guess the MIME type based on the given file extension before creating the files dictionary. There are some downfalls with that, e.g. what if it has no extension (blobs, etc.) but this seems like the best option: https://docs.python.org/3.8/library/mimetypes.html#mimetypes.guess_type

Hm, no news around that bug on new python releases
