/**
* Parses/writes account properties from/to a {@link Config} file.
*
* <p>This is a low-level API. Read/write of account properties in a user branch should be done
* through {@link AccountsUpdate} or {@link AccountConfig}.
*
* <p>The config file has one 'account' section with the properties of the account:
*
* <pre>
* [account]
* active = false
* fullName = John Doe
* displayName = John
* preferredEmail = john.doe@foo.com
* status = Overloaded with reviews
* </pre>
*
* <p>All keys are optional.
*
* <p>Not setting a key and setting a key to an empty string are treated the same way and result in
* a {@code null} value.
*
* <p>If no value for 'active' is specified, by default the account is considered as active.
*
* <p>The account is lazily parsed.
