use bcrypt as default password hashing algo 
argon2id has a high memory cost and, if not properly tuned, it can lead to
resource starvation.

Advanced users can still configure and use argon2id.
Passwords stored as argon2id will continue to work

add, optional, in memory password caching 
Verifying argon2 passwords has a high memory and computational cost,
by enabling, in memory, password caching you reduce this cost

For TLS auth, the certificate common name must match the name provided
using the "USER" FTP command

Use new methods in the io and os packages instead of ioutil ones 
ioutil is deprecated in Go 1.16 and SFTPGo is an application, not
a library, we have no reason to keep compatibility with old Go
versions.

Go 1.16 fix some cifs related issues too.

REST API v2 
- add JWT authentication
- admins are now stored inside the data provider
- admin access can be restricted based on the source IP: both proxy
  header and connection IP are checked
- deprecate REST API CLI: it is not relevant anymore

Some other changes to the REST API can still happen before releasing
SFTPGo 2.0.0

Accept a config file path instead of a config name 
Config name is a Viper concept used for searching a specific file
in various paths with various extensions.

Making it configurable is usually not a useful feature
as users mostly want to define a full or relative path
to a config file.

This change replaces config name with config file.
