    directory as appropriate.

    If you are modifying or removing an existing 'show', 'config' or 'sonic-clear'

#### What I did
Change the DB connection in `scripts/sensorshow` to use TCP socket.

#### How I did it

#### How to verify it
Run the commands that invoke `sensorshow` (e.g. `show platform voltage`) without `write` permission to see if it's returning the correct output instead of the `RuntimeError: Unable to connect to redis (unix-socket) - Permission denied(1): Cannot assign requested address` error

#### Previous command output (if the output of a command-line utility has changed)
 `RuntimeError: Unable to connect to redis (unix-socket) - Permission denied(1): Cannot assign requested address`

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