Context

In #158 we've introduces CORS settings in configuration. As a next step we want to reuse same generic CORS settings for containers across all FrostFS gateways, including S3 Gateway. See more in TrueCloudLab/frostfs-s3-gw#641

Proposal

Consider existing CORS configuration as an override for new CORS settings mechanism. New CORS settings mechanism consist of having separate CORS container with CORS objects inside. Format of the CORS object is defined in S3 Gateway.

We need to:

Define CORS container in a config
Support the search of CORS object in the container
Apply CORS headers based on the data in the CORS object the same way it is done in S3 Gateway
Override these settings if cors config values are defined
