Why I'm doing:

Paimon enables CachingCatalog by default from 0.9.0. This PR optimizes Paimon metadata cache usage, default params are as follows:

        // cache expire time, set to 2h
        this.paimonOptions.set("cache.expiration-interval", "7200s");
        // max num of cached partitions of a Paimon catalog
        this.paimonOptions.set("cache.partition.max-num", "1000");
        // max size of cached manifest files, 10m means cache all since files usually no more than 8m
        this.paimonOptions.set("cache.manifest.small-file-threshold", "10m");
        // max size of memory manifest cache uses
        this.paimonOptions.set("cache.manifest.small-file-memory", "1g");

Users can change this options by adding propeties like paimon.option.xxxx when creating the paimon catalog.
