* created a "Log" function for type "Connection"
* created a "log" function for type "Provider"
* replace logger calls to Log/log where possible

This will show the key fingerprint and the associated comment, or
"password" when password was used, during login.
Eg.:
```
message":"User id: 1, logged in with: \"public_key:SHA256:FV3+wlAKGzYy7+J02786fh8N8c06+jga/mdiSOSPT7g:jo@desktop\",
```
or
```
message":"User id: 1, logged in with: \"password\",
...`

Added a compatibility layer that will convert newline delimited keys to array
when the user is fetched from the database.
This code will be removed in future versions please update your public keys,
you only need to resave the users using the REST API.
