The openstack shell is missing autocompletion and sub-subcommands

[Andrea Ieri]

When using the standard python3-openstackclient package, it is possible to enter the openstack shell by invoking the openstack binary without any subcommand. Within the shell, subcommands can be autocompleted.

Doing the above with the snap openstack client yields a semi-functional shell. Autocompletion is not available, and any 2nd level subcommand fails:

(openstack) server list
usage: server list [-h] [-f {csv,df-to-csv,json,table,value,yaml}] [-c COLUMN]
                   [--format-config-file FORMAT_CONFIG]
                   [--max-width <integer>] [--fit-width] [--print-empty]
                   [--quote {all,minimal,none,nonnumeric}] [--noindent]
                   [--sort-column SORT_COLUMN]
                   [--reservation-id <reservation-id>]
                   [--ip <ip-address-regex>] [--ip6 <ip-address-regex>]
                   [--name <name-regex>] [--instance-name <server-name>]
                   [--status <status>] [--flavor <flavor>] [--image <image>]
                   [--host <hostname>] [--all-projects] [--project <project>]
                   [--project-domain <project-domain>] [--user <user>]
                   [--user-domain <user-domain>] [--long] [-n]
                   [--marker <server>] [--limit <num-servers>] [--deleted]
                   [--changes-since <changes-since>]
server list: error: unrecognized arguments: list

Double tapping TAB within the shell normally lists all the available commands, but when using the snap only the following is shown:

(openstack)
alias edit exit help history load py pyscript quit set shell shortcuts unalias

Running full openstack commands from bash (e.g. `openstack server list`) works as expected.

Hello,

I was going to open a new bug but this is related.
You cannot also load the auto completion in your shell (bash in this case)

$ . <(openstack complete)
No module named 'vitrageclient.v1.cli.webhook.WebhookShow'; 'vitrageclient.v1.cli.webhook' is not a package

I've added support for auto-completion from outside of the openstack CLI shell but I'm a bit stumped as to why its not working from within the shell.
