Feature: feed private key from memory

[dpogorzelski]

Currently vssh.GetConfigPEM() function expects to read the key from a file on disk via:
key, err := ioutil.ReadFile(keyFile)
but when using vssh as a library it can be not very convenient to generate a new key, write it to disk and then read it from disk again in GetConfigPEM(). Instead it would be great to have the option to generate a private key and feed it directly from memory to either GetConfigPEM() or a similar function like GetConfigFoo(user string, block *pem.Block) or GetConfigFoo(user string, block []byte).
Let me know what are your thoughts :)

vSSH uses standard ssh client config from Go ssh library (*ssh.ClientConfig) so developer can create their own function to generate it. as you said you can create GetConfigFoo(.....) *ssh.ClientConfig

vs := vssh.New().Start()
config := GetConfigFoo(........)
vs.AddClient("54.241.122.224:22", config, vssh.SetMaxSessions(4))
.
.
.
func GetConfigFoo(.....) *ssh.ClientConfig {

}

In fact I added the GetConfigPEM as sample at helper Go file but what I like in this case is remote secret managements like Vault Hashicorp. I think getting the pem block from them is a great solution!

This is a good point thanks :)
