using default_scheduler_url as a mounting point (not root http://address/mount) behind proxy not working

[franckOL]

I need to mount luigi behind a nginx, for example luigi at http://address/mount.
For that I configure:

[core]
default_scheduler_url=http://address/mount
....

GUI is ok and works but, CLI not due to url resolution. it happens there

luigi/luigi/rpc.py

Line 54 in c135664

def _urljoin(base, url):

To understand what happened:

parsed=urlparse('http://address/mount')
url='/api/add_task'
urljoin(parsed.geturl(), url)
# ==> give 'http://address/api/add_task'
# expected http://address/mount/api/add_task

What I must do for working - slash at the end of mount point, no slash for url -:

parsed=urlparse('http://address/mount/')
url='api/add_task'
urljoin(parsed.geturl(), url)
# ==> http://address/mount/api/add_task

I think having the slash is expected.
