refactor(dataproxy): TLS Client Auth

Browse Source 
Use a SecureJsonData field for TLS
Client Auth instead of 3 new db
fields. Same model as used for
PluginSettings.

Saves and encrypts the pem file
content rather than just saving
the paths to the cert and key.
This allows for uploading from
the Edit Datasource page in
Grafana.
