feat: support table options

[v0y4g3r]

I hereby agree to the terms of the GreptimeDB CLA

What's changed and what's your intention?

Allow user to specify table options when creating table. These options are also persisted to manifest/metasrv.

We can now creating table like:

CREATE TABLE monitor (
    host STRING,
    ts TIMESTAMP,
    cpu DOUBLE DEFAULT 0,
    memory DOUBLE,
    TIME INDEX (ts),
    PRIMARY KEY(host)
) ENGINE=mito WITH(regions=1, ttl='1day', write_buffer_size='32KB');

The table options are persisted to table manifest:

$ cat  /tmp/greptimedb/data/greptime/public/1024/manifest/00000000000000000000.json | jq
...
        "options": {
          "write_buffer_size": "32KiB",
          "ttl": "1day",
          "extra_options": {
            "regions": "1"
          }
        },
        "created_on": "2023-02-20T09:58:50.390371Z"
      },
      "table_type": "Base"
    }
  }
}

Also in this PR, regions now respect user specified max_write_buffer_size when creating table. Table engine will create a SizeBasedStrategy with that value for each region.
