bug#54758: auth-source plstore encryption

[Andrew Cohen]

Tags: patch

In the plstore backend in auth-source all tokens are stored unencrypted
with the exception of the "secret". But it is necessary/convenient to
store other items encrypted as well (especially for use with oauth2)
such as the client-secret, and the refresh and access tokens. This small
patch adds the ability to specify which tokens should be stored in
encrypted fashion.
