[SED] Wipe SSD CLI

[ShauliTaragin]

HLD: sonic-net/SONiC#2449
This PR is dependent on: sonic-net/sonic-platform-common#712

What I did

I added a CLI to securely wipe the switch SSD (crypto + block erase).

How I did it

I added the wipe-ssd command under the existing 'config sed' group,
using the platform chassis. It displays an irreversibility warning
prompt (bypassable with -y) and delegates to SedMgmt.wipe_ssd().

How to verify it

config sed wipe-ssd

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)
