METRON-505: Add environment variable and system property functions to the Stellar language
Tested in quick-dev from the Stellar REPL.
Build the platform, as normal. The new functions will get picked up automatically on the classpath via the annotations.
**Examples:**
```
SYSTEM_ENV_GET for exposing environment variables
[root@node1 bin]# export MIKE_VAR="blah blah blah"
[root@node1 bin]# echo $MIKE_VAR
blah blah blah
[Stellar]>>> mikevar := SYSTEM_ENV_GET('MIKE_VAR')
[Stellar]>>> mikevar
blah blah blah
SYSTEM_PROPERTY_GET for exposing system properties
[Stellar]>>> prop := SYSTEM_PROPERTY_GET( 'os.name' )
[Stellar]>>> prop
Linux
[Stellar]>>> prop := SYSTEM_PROPERTY_GET( 'user.name' )
[Stellar]>>> prop
root
```

> Stellar and the Stellar REPL allow you assign variables and compose functions for use in parsing, enrichment, and threat triage. There is currently no mechanism for extracting values from environment variables and Java system properties. This Jira tracks adding functions for exposing this functionality in Stellar.
