Information system code cleanup for arc7
Description
Removal of EMIES, gridftp, fix some related bugs, removal of other legacy features
The following ARC6 features have been removed:
- EMIES endpoints
- GridFtp endpoint
- multiple controldirs
- remote grid manager
- dependencies between gridftp block and nordugrid
- Reading of gridmapfiles and all related errors and warnings
The following notable changes will affect clients:
- Nordugrid schema no longer publishes any gridftp endpoint
- Nordugrid schema job ids are now the same as REST, but they're not published anyway
- Due to a bug in the GLUE2 schema only REST 1.1 endpoint version is published
- Removal of user scanning might affect some special options such as
sessiondir=*which needs some testing.
The changes have been tested and it seems to work as expected.
