Title: Implement the LFN auto completion in File Catalog CLI

Dear all,

I add some code so that the user can auto complete the LFN in the CLI.

Almost all commands which need LFN can do the auto completion work, except for `ls` command (Because there are some problems.).

For an example (you can use TAB to auto complete LFN.):

```
FC:/> size -l /
BES3/ bes/ caitriana/ offline/
FC:/> size -l /BES3/
directory: /BES3
