Support the configuration API for generic configuration providers

Feature request type

enhancement

Is your feature request related to a problem? Please describe

Currently, when running the garnet server we must provider either command-line arguments or a garnet.conf JSON file. By adopting the https://learn.microsoft.com/en-us/dotnet/core/extensions/configuration we will be able to use any configuration provider and require less manual work for maintaining the Options file

Describe the solution you'd like

building on top of #579 we would call builder.Configuration.AddEnvironmentVariables(prefix: "GARNET_") (see https://learn.microsoft.com/en-us/dotnet/core/extensions/configuration-providers#prefixes)
