WKBCH-14: Add cloudserver server-access.log and FluentBit for bucket logging

[dvasilas]

• Add a logs volume to cloudserver
• Enable serverAccessLogs in cloudserver config when access_logging is enabled
• Add Fluentbit service
• Remove accountDismplayName from access_logs table (S3C-10745)

Nit: seems like quite a duplication of code, I don't have the gotemplate syntax in mind to suggest but can we focus on only modifying mode to DISABLED/ENABLED?

I changed it to

    "serverAccessLogs": {
    {{ if .Features.AccessLogging.Enabled }}
        "mode": "ENABLED",
    {{ else }}
        "mode": "DISABLED",
    {{ end }}
        "outputFile": "/logs/server-access.log",
        "highWaterMarkBytes": 10485760,
        "retryReopenDelayMS": 1000,
        "checkFileRotationIntervalMS": 10000
    },

It seems to work, but adds two blank lines

    "serverAccessLogs": {
    
        "mode": "ENABLED",
    
        "outputFile": "/logs/server-access.log",
        "highWaterMarkBytes": 10485760,
        "retryReopenDelayMS": 1000,
        "checkFileRotationIntervalMS": 10000
    },

Cloudserver starts, so I didn't try to remove them.

That's fine, it doesn't have to be pretty, as long as it's accurate. If you want to fix it you can by placing the - around the template, like this (I just placed them randomly, I can never remember exactly how they work):

    {{ if .Features.AccessLogging.Enabled -}}
        "mode": "ENABLED",
    {{ else -}}
        "mode": "DISABLED",
    {{ end -}}

But optional, at least code wise we have no duplicate now 👍
