FUS-5906: Provide Jira Recipe and documentation

[DavidDwyer87]

• updates to jira asciidoc
• add attachment support the configuration

[mcondo]

Change to: Add Used with pagination feature. This variable is used to set the startAt query parameter, which is used to traverse the pagination. Jira pagination is zero-index-based. This means the first page number is 0.

[mcondo]

This recipe is configured to use pagination by batch size. Needs to configure Query Params, and the property 'Pagination By BatchSize'
Query Params:

• maxResults=${LW_BATCH_SIZE}, where ${LW_BATCH_SIZE} is a variable
• startAt=${LW_INDEX_START}, where ${LW_INDEX_START} is a variable

2. Configure the 'Pagination By BatchSize' properties

• IndexStart: The starting point. Set to 0 because the Atlassian pagination is zero-index-base. From the queries above, it replaces variable ${LW_INDEX_START}, the plugin internally increases the value of the indexStart ensuring each page is requested with an updated start-point.
• BatchSize: The number of elements to retrieve. Set to 50 by default. From the queries above, it replaces variable ${LW_BATCH_SIZE}
• Stop Condition Key: Reference the “key” in the response, that needs to be met in order to stop the pagination. To paginate issues, it must be “issues”, to paginate projects it must be 'values'
• Stop Condition Value: Reference the “value” in the response, that needs to be met in order to stop the pagination. For the jira config, to stop pagination the list of objects retrieved must be empty, then the stop condition should be []

Need to change to `"parentNestedData": "fields.attachment[*]", otherwise the attachment metadata list will not be extracted
