Provide option to disable block mark deletion and mark no compaction from bucket UI

[yeya24]

In Prometheus, admin level functionalities like delete series are not provided through UI.
But in Thanos, now it is supported to mark deletion and mark no compaction from bucket UI. This is an admin-level operation and requires admin permissions. Some users might not want to expose those functionalities from bucket UI to their users.

We can have an option to disable those functionalities from UI or make those features not enabled by default.

@Vaani-pathariya https://thanos.io/tip/thanos/quick-tutorial.md/ is a great resource to start.
This issue doesn't require much knowledge about Thanos. Some UI/backend knowledge is good enough.

@yeya24 Do you want a checkbox to disable block mark deletion and mark no compaction or to disable them by default?
I far as I can understand if it's disabled by default, admins cant enable this using flags as I didn't find any flag like this and users also won't be able to access it. If there is a checkbox for it to be enabled, I currently don't know if there is a separate UI setup for admins and users so that admins can make it available to users if they want through the UI.
If nobody else is working on the issue I can give it a try!!

@harsh-ps-2003 I think we want a new flag to disable this functionality. When the flag is set, users shouldn't be able to add markers in the UI.
I don't think we need to add any checkbox in the UI itself
