[replicaJunction]

Extend support for issues by adding methods for issue links:

api/2/issueLink

• [x] New-JiraIssueLink
  • -Type Jira.IssueLinkType?
  • -InwardIssue Jira.Issue
  • -OutwardIssue Jira.Issue
  • -Comment
    • body
    • visibility
  • POST /rest/api/2/issueLink
• [x] Get-JiraIssueLink
  • -Issue Jira.Issue
    • Get all issue Links from the issue (property of GET /rest/api/2/issue/{issueIdOrKey})
  • -Link int/Jira.IssueLink
    • GET /rest/api/2/issueLink/{linkId}
• [x] Remove-JiraIssueLink
  • -Link int/Jira.IssueLink
    • DELETE /rest/api/2/issueLink/{linkId}

api/2/issueLinkType

• [x] Get-JiraIssueLinkType
  • no parameter: GET /rest/api/2/issueLinkType
  • -Link int/Jira.IssueLink: GET /rest/api/2/issueLinkType/{issueLinkTypeId}
• [ ] New-JiraIssueLinkType POST /rest/api/2/issueLinkType
  • -Name string
  • -Inward string
  • -Outward string
• [ ] Remove-JiraIssueLinkType DELETE /rest/api/2/issueLinkType/{issueLinkTypeId}
  • -LinkType int/Jira.IssueLinkType
• [ ] Set-JiraIssueLinkType or Update-JiraIssueLinkType PUT /rest/api/2/issueLinkType/{issueLinkTypeId}
  • -LinkType Jira.IssueLinkType mandatory
  • -Name string optional
  • -Inward string optional
  • -Outward string optional
  • Out of all optional parameters, at least one must be provided. This shall be controlled with ParameterSetName

This issue is NOT about Remote Issue Links - although that would be a cool thing to have access to through PowerShell, that looks like it will be more time intensive to implement, so I'm not ready to tackle that just yet. Remote Issue Links were implemented with #80

Probably going to need a new function, Get-JiraIssueLinkType, to make the link types more discoverable (similar to issue transitions).

The API also seems to support updating link types, but that's not as big of a concern at the moment - I'm guessing most people would rather perform those types of changes from the GUI.

75ba2d6 adds the Get-JiraIssueLinkType function.

I have updated the branch (merged with master).

What is missing in order to create a PR?
