Add API Token Auth Support

[spamhome]

Add the support for auth with API Token

How it works

the class now parse the password parameter ($this->password). if there a ":" in password they will be use token authentification.

if not the class is use username + password authentification

So the class is compatible backwards

How to use

Login with username & password: $pve2 = new PVE2_API("hostname", "username", "realm", "password");

Login with API Token: $pve2 = new PVE2_API("hostname", "username", "realm", "TokenID:TokenValue");

Example: $pve2 = new PVE2_API("hostname", "root", "pam", "TestToken:7381a050-0185-43d1-a651-0c30a2bba5cc");

I think that using the presence of a colon in the password is too unpredictable, especially in current times.

Perhaps if the password field is null when PVE2_API is initiated, a new field in the request can be checked?

1. hostname
2. username
3. realm
4. password
5. ticket
