standalone-config.properties should be included when standalone create the segmentstore

[CharlieLChen]

Describe the bug
In #6511, we know we can specify the JAVA_OPTS to configure the publishedIPAddress, the problem is that passing configuration to system property is the only option we can choose to configure the segmentstore. Not all of configuration in standalone-config.properties could take effect as the standalone only include the configuration from the system property:

pravega/standalone/src/main/java/io/pravega/local/InProcPravegaCluster.java

Line 293 in a5aa4a2

.include(System.getProperties())

I know there is a workaround for that, but the configuration in standalone-config.properties should take effect, otherwise it will be very stranger.

How to fix
I think adding the following code will work.

                .include(new Properties("./config/standalone-config.properties") )

I will create a PR for this one tomorow.
