Add config for http.expectContinue=true / false ?

[Stefan CORDES]

Hi,
we have some issues with introduced http 100 expect continue with our nexus3. 
(see https://github.com/sonatype/nexus-public/issues/287 )

Maybe it is a good idea to offer a config setting ( 
https://maven.apache.org/resolver/configuration.html )

aether.connector.http.expectContinue
Flag indicating the http client sends an Expect "100-continue" when putting 
files.
Default "true"

?

(With that setting we could use recommended http-transport with 
-Daether.connector.http.expectContinue=false)

Workaround today is to take maven.resolver.transport=wagon with maven 3.9
and configure wagon in the settings.xml to not use expect continue

                     <httpConfiguration>

                       <all>

                         <params>

                           <property>

                             <name>http.authentication.preemptive</name>

                             <value>%b,true</value>

                           </property>

                           <property>

                             <name>http.protocol.expect-continue</name>

                             <value>%b,false</value>

                           </property>

                         </params>

                       </all>

                     </httpConfiguration>


Gruß,
Stefan
