[Bug 1799167] [NEW] nova-serialproxy missing dependency on python-websockify

[Mike Joseph]

Public bug reported:

Description:    Ubuntu 18.04.1 LTS
Release:        18.04

ii  nova-serialproxy                   2:17.0.5-0ubuntu2      all
OpenStack Compute - serial proxy

It appears that the nova-serialproxy package depends on python-
websockify, but no such dependency is currently declared for the
package.  When nova-serialproxy is installed without python-websockify,
the following errors are observed in syslog:

Oct 22 08:13:42 ctrl01 nova-serialproxy[24100]: Traceback (most recent call last):
Oct 22 08:13:42 ctrl01 nova-serialproxy[24100]:   File "/usr/bin/nova-serialproxy", line 6, in <module>

Oct 22 08:13:42 ctrl01 nova-serialproxy[24100]:     import websockify
Oct 22 08:13:42 ctrl01 nova-serialproxy[24100]: ImportError: No module named websockify

However, if python-websockify is manually installed using apt, the
errors resolve and the nova-serialproxy daemon is able to start.
