Introduce a new component to manage trusted certificates in IAM

[ashanthamara]

Description

With the introduction of pre-update-password extension(#21202) there is a requirement to store certificates. Managing that only for this extension requires a new table as certificates only apply for this particular extension. While evaluating, note that the IDN_CERTIFICATE table holds the certificates configured in the applications of the system used to validate signatures or encrypt data received and sent to apps. After evaluating the possible ways it is decided to store the certificates related to the pre-update-password extension in the IDN_CERTIFICATE table and consider that table as a central table to manage certificates of a tenant.

With that decision we need a central component to manage the CRUD operations related to the certificates.
