Support configurations for multiple JIRA projects

[robertjahn]

Currently, the JIRA service has its configuration in the jira-details secret and only allows for defining one project.

Perhaps some JSON conf file can contain this setup. Here is a mockup

{
	"jira-base-url": "https://MYORG.atlassian.net",
	"jira-username": "[email protected]",
	"jira-api-token": "MYTOKEN",
	"projects": [
                 {
			"jira-project-key": "AA",
			"jira-issue-type": "Keptn SLO Evaluation",
			"jira-create-ticket-for-problems": "DD",
			"jira-create-ticket-for-evaluations": "DD",
			"jira-default-problem-status": "In Progress",
			"jira-default-evaluation-status": "Done"
		},
		{
			"jira-project-key": "BB",
			"jira-issue-type": "Keptn SLO Evaluation",
			"jira-create-ticket-for-problems": "DD",
			"jira-create-ticket-for-evaluations": "DD",
			"jira-default-problem-status": "In Progress",
			"jira-default-evaluation-status": "Done"
		}
	]
}
