HANA database secrets engine not working because of outdated driver

[holgpar]

Describe the bug

The HANA database secrets engine fails to connect to cloud hosted HANA instances.

I tried to use the same connection URL with a recent version of the golang driver for HANA and it worked. Then I found that the version of the driver used by vault is 5 years out of date.

Conclusion: It does not make sense to debug this further. The driver should be updated.

To Reproduce Steps to reproduce the behavior:

1. Run

   vault write my-database/config/dev-db \
   plugin_name=hana-database-plugin \
   connection_url="hdb://DBADMIN:PASSWORD@4f1ea423-8984-4091-aaca-ed83a7d75723.hana.prod-eu12.hanacloud.ondemand.com:443?TLSServerName=4f1ea423-8984-4091-aaca-ed83a7d75723.hana.prod-eu12.hanacloud.ondemand.com" \
   

It fails with:

* error creating database object: error initializing db: error verifying connection: SQL Error 10 - authentication failed: Detailed info for this error can be found with correlation ID 'F012E4E1AC03C34ABE4E3D7A261B89E9'

Expected behavior The connection is successful.

If you want I can help you with updating the driver (however I have no experience with your code base...)
