Allow sfdx force:source:retrieve/deploy for InboundCertificate

[berginrp]

Is your feature request related to a problem? Please describe.
We have a lot of API clients that have automated certificate rotation. But Salesforce's inbound certificate doesn't have any automation to upload the inbound cert. This has resulted in downtime for the APIs due to expired certificates, though we try to keep track of the expiring certificates manually.

What are you trying to do
I'd like to retrieve and deploy inbound certificates and automate the process using CI/CD.

Describe the solution you'd like
Need support for sfdx force:source:retrieve -m InboundCertificate:CertName and sfdx force:source:deploy -m InboundCertificate:CertName

Describe alternatives you've considered
The current alternative is a manual process to keep track of expiring certificates and upload. Sometimes this is causing production downtime.

Additional context
Currently when I try sfdx force:source:retrieve -m InboundCertificate:CertName, I get the following error.
ERROR running force:source:retrieve: The specified metadata type is unsupported: [InboundCertificate]
