JIRA2GitLab integration

Adds the ability to create and access branch on GitLab directly from the popup menu of JIRA tab. ✅ All information is stored offline on your workstation, no information is collected. ❕ GitLab Search API is known for working "unstable" and work with few seconds delay, results are provided as-is and all search related issues are related to API itself. Newly created branches may take up to 10s to be returned in the search results. ⚠️Chrome does not provide secure storage by default, and as this plugin is not using any user authentication from where the encrytion key could be derived - the API token (with read and write acces as needed per functionality) is stored in chrome storage as cleartext. Make sure you are limiting access to the workstation to avoid security breaches.
