0018  * Sets resource limits on a quota root.
0019  *
0020  * Quotas are defined with respect to "resources" and "quota roots".
0021  * A resource is a numerical property that can be limited, such
0022  * as the octet size of all the messages in a mailbox, or the
0023  * number of messages in a mailbox.  Each mailbox has one or more
0024  * quota roots, which are where the resource limits are defined.
0025  * A quota root may or may not be a mailbox name, and an empty
0026  * string is a valid quota root.  All mailboxes with the same quota
0027  * root share the resource limits of the quota root.
0028  *
0029  * This job can only be run when the session is in the
0030  * authenticated (or selected) state.
0031  *
0032  * This job requires that the server supports the QUOTA
0033  * capability, defined in
0034  * <a href="https://tools.ietf.org/html/rfc2087">RFC 2087</a>.
