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.
