[geotk] migration to java 11

[juergen sorg]

hi martin,

where is the maven repo for this dependency?:
 >          <dependency>
 >              <groupId>org.geotoolkit</groupId>
 >              <artifactId>geotk-client-csw</artifactId>
 >              <version>5.0-SNAPSHOT</version>
 >          </dependency>

i tried it with

<dependency>
			<groupId>org.geotoolkit</groupId>
			<artifactId>geotk-client-csw</artifactId>
			<version>5.0.0-MC0082</version>
		</dependency>

and was able to compile and deploy my app successfully. but at runtime i 
got exception [0] when instantiating CatalogServicesClient. i changed 
CatalogServicesServer to CatalogServicesClient, because 
CatalogServicesServer does not exist any more.

because of compilation errors i added dependencies [1] and removed [2] 
because it does not exists. additionally, i replaced the 2 geotk 
dependencies with apache sis [3]

regards,
juergen
