Codec output directory is hardcoded

[emre-aydin]

Java codec generator assumes the codecs will be generated under the IMDG project and assumes its directory structure. We now require them to be generated under MC repository to be able to evolve the codecs independently from IMDG releases.

For this to work, we can follow either of the following two ways:

1. Make the following four lines to be configurable

hazelcast-client-protocol/util.py

Line 202 in 81b91c3

SupportedLanguages.JAVA: 'hazelcast/src/main/java/com/hazelcast/client/impl/protocol/codec/',

hazelcast-client-protocol/util.py

Line 211 in 81b91c3

SupportedLanguages.JAVA: 'hazelcast/src/main/java/com/hazelcast/client/impl/protocol/codec/custom/',

hazelcast-client-protocol/binary/util.py

Line 313 in e764335

SupportedLanguages.JAVA: 'hazelcast/src/test/java/com/hazelcast/client/protocol/compatibility',

hazelcast-client-protocol/binary/util.py

Line 322 in e764335

SupportedLanguages.JAVA: 'hazelcast/src/test/resources',

2. Deduce the output directories automatically from the namespace argument (converting the package name to a directory structure, i.e. when com.hazelcast.webmonitor.client.impl.protocol.codec is passed, classes will be generated under <ROOT-DIR>/src/main/java/com/hazelcast/webmonitor/client/impl/protocol/codec/).
