v1.1.0

This is a major release featuring some infrastructure improvements and some minor API breakage.

Breaking changes:

• The custom metaclass that was once in omniduct has now been extracted into its own library, and gained support for checking that subclasses correctly override methods. Subclasses that override methods defined on a parent class must now explicitly annotate those method declarations with interface_meta.override(). Any downstream subclasses will have to conform to these changes also.

New features:

• FilesystemClients can now have the home directory specified at instantiation or overridden at runtime, and can now be configured to be read only.
• DatabaseClients now propagate the instantiation-time schema/database/etc namespace configuration as defaults to utility methods (such as table_desc, table_list, etc).

Bugfixes and improvements:

• SQLAlchemy schema exploration extensions are now more dialog agnostic (#93)
• The 'replace' operation for the DatabaseClient.query_to_table method has been fixed for Presto and HiveServer2.
• REST client logging now renders JSON error responses rather than simply showing a string representation.
