Feature Request: Add support for custom fields

[felickz]

customfields themselves are just an additional key/value pair passed to the fields object: https://developer.atlassian.com/server/jira/platform/jira-rest-api-examples/#creating-an-issue-using-custom-fields

Ideally the custom field would be an arbitrary map the user passes into the github action. (inspiration for this from here)

Currently a failure will look like:

jira.exceptions.JIRAError: JiraError HTTP 400 url: ...
response text = {“errorMessages”:[],“errors”:{“customfield_#####”:“<field> is required.“}}”

Could you elaborate how you would want to use this?

Our primary approach to configuring the actions is through environment variables. One way would be to add something like a JIRA_CUSTOM_FIELDS variable which could contain a formatted string with key/value pairs for custom fields. The values would be static though.

As far as I can tell the underlying JIRA library that we use also supports custom fields.
