connector:issue deprecates --database, --table and --time-column options

[takkanm]

now --database and --table is obsolete

ref #67

[takkanm]

@nahi @muga please, review it.

[frsyuki]

Discussion at #67 includes an idea to include database and table names in out: section of config file. And I think that is better. If we take that way, adding this code will create another obsoleted code (which can't be removed in fact) in the future.

@muga Do you think it's better to set db and table names at cmdline argument?

[frsyuki]

This change is not backward compatible. This makes existent automated shell scripts failed which are using --database and --table options.

[takkanm]

Sorry. I'll fix it.

[takkanm]

I fixed following items.

• allow no argument for database, table, time-column, if config.yml include these option.
• include database, table, and time-column option in config['out'] for td-api.
• some refactoring.

[muga]

Thank you for your working:-) The fix requires platform side change. Please talk about it later.

[takkanm]

I removed argument option(database, table) . Because, these options should write to configuration file.
