sdss/sdss_access: sdss_access 1.0.0

This release is a major refactor that coincides with the release of tree 3.0.0. This release allows for versioning of paths defined in tree for use in sdss_access.

• Modified sdss_access to use the new versioned tree. Removes input and dependency on single sdss_paths.ini file.
• sdss_access no longer uses ConfigParser to parse the sdss_paths.ini file
• path templates are passed in directly from the tree python product
• The symbol for "special function" path definition has changed from % to @
• sdss_access now checks for compressed/uncompressed files on disk compared to its path template definition
• remote access classes, i.e RsyncAaccess, no longer need both public and release to be specified to access DRs. Sets public=True automatically if DR in release name.
• Added path.changelog module with new compute_changelog and get_path_templates functions to compute changes in paths between releases
• Moved tests out of sdss_access python package to top level.
• Deprecated included logger and config in favor of sdsstools logger and config.
• Simplified python package setup.cfg and consolidated requirements files
