    [TRAFODION-3145] Make "hbase_options" as default setting and use cqd …

    …to change the default setting
    
    As we know, for performance thinking, we always need to add below syntax in “create
table” syntax. And I know in latest version, we have made “ATTRIBUTES ALIGNED FORMAT”
as default, do we have a plan that make HBASE_OPTIONS(including ENCODING、COMPRESSION、MEMESTORE)
as the default setting when creating table? I think this will be easier for end users?
    ATTRIBUTES ALIGNED FORMAT
    HBASE_OPTIONS
    (
    DATA_BLOCK_ENCODING = 'FAST_DIFF',
    COMPRESSION = 'SNAPPY',
    MEMSTORE_FLUSH_SIZE = '1073741824'
    )
    ;
    
    Trafodion has
    cqd HBASE_DATA_BLOCK_ENCODING_OPTION ‘FAST_DIFF’;
    cqd HBASE_COMPRESSION_OPTION ‘SNAPPY’;
    
    Add 
    cqd HBASE_MEMSTORE_FLUSH_SIZE_OPTION '1073741824' ;
    
    So one can use these values without explicitly specify them when create table.
