[FEATURE REQUEST] Use Spring configuration instead of custom variables

[yogendra]

Currently, documented procedure for supplying database information is node,port, dbname, etc. We can use standard spring attributes instead. You can provide these via program argument, JVM Argument or Environment variables. Here is a quick ref list

Description	JVM Arg / Program Arg	Environment Var
DB Server Name	spring.datasource.hikari.data-source-properties.serverName	SPRING_DATASOURCE_HIKARI_DATA_SOURCE_PROPERTIES_SERVERNAME
DB Server Port	spring.datasource.hikari.data-source-properties.portNumber	SPRING_DATASOURCE_HIKARI_DATA_SOURCE_PROPERTIES_PORT
DB Name	spring.datasource.hikari.data-source-properties.databaseName	SPRING_DATASOURCE_HIKARI_DATA_SOURCE_PROPERTIES_DATABASENAME
DB User	spring.datasource.hikari.username	SPRING_DATASOURCE_HIKARI_USERNAME
DB Password	spring.datasource.hikari.password	SPRING_DATASOURCE_HIKARI_PASSWORD

@yogendra I created the short variables to ease with the typing the name in the the script. I can replace them with regular environment variables but then it makes it harder to type it in. Most folks(SEs) create the start.sh script and pass the values as -D parameters. Thoughts?

[yogendra]

Yeah works that way too.
