vtkPTSFileSystem: Allow to browse both local and remote locations

Christos Tsolakis requested to merge christos.tsolakis/paraview:allow-client-browsing-in-filesystem-microservice into master

The filesystem microservice can now browse both local and remote locations by passing an extra location parameter. location can be:

  • Client (i.e. local)
  • Data Service
  • Render Service
  • Server = Data Service (for now, can become IO Service in the future)

The relevant values are really Client and Server but we add separate service destinations in case we need it in the future (also communication is really between client and services not client and server).

To avoid having to re-implement all filesystem operations for both local and remote locations we introduce a new vtkLocalFileSystemProvider which inherits from vtkRemoteFileSystemProvider. vtkLocalFileSystemProvider allows to keep the code duplication low by treating it as remote i.e. we create communicate with it though vtkPackets but the actual operation are performed by the client thread. That way any new operation of vtkRemoteFileSystemProvider will automatically work for vtkLocalFileSystemProvider.
