Adds a button to the findings for related issues

What does this MR do?

This MR help link together findings with their related issue ion GitLab. It does so by replicating our current manual process for this using the REST API. There's some other bits in there too to help with the rate limiting.

Here's a breakdown of how it works.

    A[Extract Component Label and filename]
    C[Build API endpoint to search issues with\ncomponent label and filename in title]
    D{Issue found?}
    E(Show Issue Link)
    F{Rate Limit Reached?}
    G[Extract Component description]
    H[Use gathered information to create link for a new issue]
    I(Show Create issue link)
    J(Show 'check failed')
    K[Check Local Storage for issue]
    L{Issue Found?}
    M[Store issue link in local storage]
    N[Fetch API Endpoint]

A  --> K --> L
L --YES--> E
L --NO--> C

C --> N --> D
D --YES--> M --> E:::endResult
D --NO--> F

F --YES--> J:::endResult
F --NO--> G --> H --> I:::endResult

To get this new information on in the drawer, I re-jigged the design a little too. Here's a before and after:
