[PATCH 01/13] defconfigs: add NFS testing configurations

[Luis Chamberlain <mcgrof@kernel.org>]

Add five defconfigs for NFS testing:

NFS filesystem testing configurations:
- nfs-fstests: Filesystem testing suite (fstests) on NFS mounts
  * Enables pNFS section for testing with pNFS-capable exports
  * Tests NFSv4.2, v4.1 with pNFS export capability
- nfs-gitr: Git regression testing on NFS mounts
  * Tests git operations on NFS with pNFS export capability
  * Enables NFSv4.2 and pNFS sections for comprehensive coverage
- nfs-ltp: Linux Test Project suite on NFS mounts
  * General test suite that runs on NFS (not pNFS-specific)

NFS protocol testing configurations:
- nfstests: NFStest protocol conformance suite
  * Tests NFS protocol interoperability
  * General NFS testing (not pNFS-specific)
- pynfs-pnfs-block: PyNFS pNFS block layout protocol testing
  * Specifically tests pNFS block layout protocol conformance
  * This is the only configuration that actually tests pNFS-specific features

All configurations:
- Build kernels from Linus' tree for latest development
- Use kdevops-provided NFS server for consistent test environment
- Enable systemd journal remote for enhanced debugging
- Support 9P filesystem for efficient host-guest kernel development

Note: Most tests run on NFS mounts that may have pNFS capability enabled
on the server side, but only pynfs-pnfs-block specifically tests pNFS
protocol features.
