Set the the respective keys to the respective values. {@link #mset(string...) MSET} will
replace old values with new values, while MSETNX will not perform any operation at all even if
just a single key already exists.
<p>
Because of this semantic MSETNX can be used in order to set different keys representing
different fields of an unique logic object in a way that ensures that either all the fields or
none at all are set.
<p>
Both MSET and MSETNX are atomic operations. This means that for instance if the keys A and B
are modified, another client talking to Redis can either see the changes to both A and B at
once, or no modification at all.

@param keysvalues
@return Integer reply, specifically: 1 if the all the keys were set 0 if no key was set (at
least one key already existed)
