[202012] [techsupport] Techsupport Error Reporting pending fixes

[vivekrnv]

What I did

This PR include some fixes which were missed while manually porting the error reporting PR onto 202012 #1833.

i.e. removing -it option from the docker exec commands. to understand why the -it option was removed, refer #1723

This also include another fix which removes -d from the show ip interface command, which fails otherwise.

Note: -d option for "show ip interface" is working on master and 202106. and not for 202012. So, this change is particular to 202012.

Master:

admin@sonic-master-imge:~$ show ip interfaces -d all

202012:

admin@sonic-202012-image:~$ show ip interfaces -d all
Usage: show ip interfaces [OPTIONS]
Try "show ip interfaces -h" for help.

Error: no such option: -d

How I did it

How to verify it

• Run the show tech-support and check the return status. It should be zero. (Atleast, it was on mellanox platform. I couldn't check the functions which were platform specific)
• Run the "show techsupport" test.

Previous command output (if the output of a command-line utility has changed)

New command output (if the output of a command-line utility has changed)
