PrivateKeyFromP12File(java.io.File)

Java environments (e.g. Java 6, Android 2.3, App Engine, or All)?

All

Please describe the feature requested.

We should add a utility method, something like 
setServiceAccountPrivateKeyFromPemFile.

To get the PEM file, take the p12 file generated by the APIs Console and 
convert it to a PEM like so:

openssl pkcs12 -in xxxxx-privatekey.p12 -nodes -nocerts > secret.pem

When prompted for a password, enter "notasecret".
