CTS2F2 — BaseQueryService filter property needs to be individualized

The filter property (type Filter) on BaseQueryService does not work as an input parameter. It needs to be replaced, instead, with:

matchAlgorithm: NameOrURI

matchValue: String OPT

refType: TargetReferenceType

referenceTarget: EntityNameOrURI

Logged: https://github.com/cts2/cts2-specification/issues/32

PIM: Change the signature of restrict to the following: (Diagram below)
PSM:
Added the following elements to the 'Query' element:
<xs:element name="matchAlgorithm" type="NameOrURI" minOccurs="0">
<xs:annotation>
<xs:documentation> The match algorithm of the filter to be
applied. If a 'setOperation' is specified, the filter
will apply to the resulting aggregate.
</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="matchValue" type="core:String" minOccurs="0">
<xs:annotation>
<xs:documentation> The match value of the filter to be
applied. If a 'setOperation' is specified, the filter
will apply to the resulting aggregate.
</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="filterComponent" type="NameOrURIList"
minOccurs="0">
<xs:annotation>
<xs:documentation> The target components of the filter to
be applied. If a 'setOperation' is specified, the
filter will apply to the resulting aggregate.
</xs:documentation>
</xs:annotation>
</xs:element>

while removing the following element:
<xs:element name="filter" type="core:Filter" minOccurs="0">
<xs:annotation>
<xs:documentation> The filter to be applied. If a
'setOperation' is specified, the filter will apply to
the resulting aggregate. </xs:documentation>
</xs:annotation>
</xs:element>
