Winlogbeat Security new dashboards - Older dashboards improvements (e…

…lastic#18775)

This PR adds two new dashboards related to events added in PRs (elastic#12906, elastic#14299, elastic#15217, elastic#17517) and implements some improvements to existing winlogbeat security module's dashboard

New Dashboards

    User Logon Dashboard shows all the logon information. It allow us to keep track between logon and admin logons event between RDP connections and disconnections.
    Failed and Blocked Accounts allow us to keep track to failed logons and locked out account

Existing Dashboards

    Added Distribution groups Events (elastic#15217)
    Found that Event 4625 can be generated by two different providers: Microsoft-Windows-Security-Auditing and Microsoft-Windows-EventSystem. Filters to use only the event.code=4625 from Microsoft-Windows-Security-Auditing where added

All Dashboards

    Markdown with links all the winlogbeat security dashboards where added (following the idea of Filebeats, Auditbeat dashboards)
    image

    Visualization that use may events (like group management related visualizations)
    were modified in order to use a saved search with the relevant events for that visualization as a source (instead of using individual filters for each visualization)

    Removed the margin between panels to look in the same way that other beats dashboards

    TSVB metrics were modified to use the Entire Time Range and to use eye-friendlier colors
