  + *Revision* Library version 0.16

In this class we manage certificates relation.

This class handles certificate request and renewal through
the interaction with the TLS Certificates Operator.

This library needs that the following libraries are imported to work:

* https://charmhub.io/certificate-transfer-interface/libraries/certificate\_transfer
* https://charmhub.io/tls-certificates-interface/libraries/tls\_certificates

It also needs the following methods in the charm class:
— get\_hostname\_by\_unit: to retrieve the DNS hostname of the unit.
— get\_secret: to retrieve TLS files from secrets.
— push\_tls\_files\_to\_workload: to push TLS files to the workload container and enable TLS.
— set\_secret: to store TLS files as secrets.
— update\_config: to disable TLS when relation with the TLS Certificates Operator is broken.
