Certificate delete API – middleware

With introducing Mutual-TLS and option to add multiple certificates
there is a need to give user a possibility to remove them, for example
when they expire. This commit adds implementation of DELETE function
to TLS Certificate node, so each of them can be removed.

Beckend implementation is here:
https://gerrit.openbmc-project.xyz/c/openbmc/phosphor-certificate-manager/+/25268

Tested with uploaded multiple TLS certificates.
Other certificates remains irremovable as they were so far.
