Using PHP's "parse_str()" to parse the query string is slightly more
efficient then our own code especially when the number of fields in
the query string grows, with the additional benefit of supporting
arrays for values when brackets are present in fieldnames.
So after this commit, providing this URI string:
$string = 'tcp://127.0.0.1?metavars[]=foo&metavars[]=hoge';
Is equivalent to providing the following named array:
$array = [
'scheme' => 'tcp',
'host' => '127.0.0.1',
'metavars' => ['foo', 'hoge'],
];
Other improvements are that parsing does not break when the value of a
field contains one or more "=" and empty or incomplete "key=value"
pairs result in an empty string for "key".
When no server profile is specified, the connection factory will not push
any initialization command to the newly created connection object.
This change is mainly useful when using redis-cluster and also makes it
possible to easily inject commands such as "SCRIPT LOAD" at initialization
time by grouping everything into one common place simply by extending the
connection factory class.
