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

fix a potential race condition for pre-login and ext auth 
hooks

doing something like this:

err = provider.updateUser(u)
...
return provider.userExists(username)

could be racy if another update happen before

provider.userExists(username)

also pass a pointer to updateUser so if the user is modified inside
"validateUser" we can just return the modified user without do a new
query

bcaf283c35 memory provider: load users from a dump file 
The `memory` provider can load users from a dump obtained using the
`dumpdata` REST API. This dump file can be configured using the
dataprovider `name` configuration key. It will be loaded at startup
and can be reloaded on demand using a `SIGHUP` on Unix based systems
and a `paramchange` request to the running service on Windows.

0a025aabfd add support for Git over SSH 
We use the system commands "git-receive-pack", "git-upload-pack" and
"git-upload-archive". they need to be installed and in your system's
PATH. Since we execute system commands we have no direct control on
file creation/deletion and so quota check is suboptimal: if quota is
enabled, the number of files is checked at the command begin and not
while new files are created.
The allowed size is calculated as the difference between the max quota
and the used one. The command is aborted if it uploads more bytes than
the remaining allowed size calculated at the command start. Quotas are
recalculated at the command end with a full home directory scan, this
could be heavy for big directories.
