Bash completions not working

[sarabjeetsingh1509]

Why I did it

Bash completions are not working

Issue

Fixes #24594

How I did it

The 2 current paths in bashrc, do not exist

root@sonic:/home/admin# ls -l /usr/share/bash-completion/bash_completion
ls: cannot access '/usr/share/bash-completion/bash_completion': No such file or directory
root@sonic:/home/admin# ls -l /etc/bash_completion
ls: cannot access '/etc/bash_completion': No such file or directory
root@sonic:/home/admin#

However, /etc/bash_completion.d/ exists.
root@sonic:/home/admin# ls -l /etc/bash_completion.d/
total 23
-rw-r--r-- 1 root root 695 Sep 17 2020 acl-loader
-rw-r--r-- 1 root root 671 Sep 17 2020 config
-rw-r--r-- 1 root root 677 Sep 17 2020 connect
-rw-r--r-- 1 root root 683 Sep 17 2020 consutil
-rw-r--r-- 1 root root 653 Sep 17 2020 crm

-rw-r--r-- 1 root root 665 Sep 17 2020 pfcwd
-rw-r--r-- 1 root root 665 Sep 17 2020 rexec
-rw-r--r-- 1 root root 671 Sep 17 2020 rshell
-rw-r--r-- 1 root root 659 Sep 17 2020 show
-rw-r--r-- 1 root root 701 Sep 17 2020 sonic-clear
-rw-r--r-- 1 root root 713 Sep 17 2020 sonic-cli-gen
-rw-r--r-- 1 root root 725 Sep 17 2020 sonic-installer
-rw-r--r-- 1 root root 725 Sep 17 2020 sonic_installer
-rw-r--r-- 1 root root 761 Sep 17 2020 sonic-package-manager
-rw-r--r-- 1 root root 653 Sep 17 2020 spm
-rw-r--r-- 1 root root 707 Sep 17 2020 watchdogutil

As a result, the bash autocompletion was not working. It was only working if /etc/bash_completion.d/* was sourced.

How to verify it

root@sonic:/home/admin# show i
icmp interfaces ip ipv6
root@sonic:/home/admin# config i
interface interface_naming_mode ipv6
