Support JTDS Driver for ASE and SQL Server

[shantstepanian]

Note a possible error to test for when trying this against SQL Server:

java.lang.ClassCastException: net.sourceforge.jtds.jdbc.ClobImpl cannot be cast to java.lang.String

Hi @shantstepanian

I wanted to contribute to the project. This seems another good issue to pick.
As per my analysis, We need to create another branch similar to MsSqlJdbcDataSourceFactory with url being jdbc:jtds:sqlserver://<host>:<port>

Thanks for your interest in contributing to the project!

For this, it is also to add a similar setup to MsSqlMetadataDialect and MsSqlDbMetadataManager. Most of the changes would be to add a new "JtdsMetadataDialect", since it is the JDBC driver that spawns most of the changes in the JDBC Metadata implementation

In terms of contributing:

• See the developer guide, albeit some parts need updating. Note that we can now test via docker
• Also note the contributing guide

Feel free to ask more questions as needed
