Post merge cleanup: remove old script, consolidate test directories

[mkavulich]

DESCRIPTION OF CHANGES:

Some cleanup after the merger of the old regional_workflow repository: eliminate the outdated update_fork.pl, and move test script and readme from test/ to tests/ directory.

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)

TESTS CONDUCTED:

• cheyenne.intel
  • used build.sh to build app
  • fundamental test suite (pending)
• Jenkins

DEPENDENCIES:

CI testing will have to be updated to account for the new location of build.sh. I have corresponded with @venitahagerty and @danielabdi-noaa to make sure they are in the loop and can apply the appropriate changes.

DOCUMENTATION:

None

Addresses a few items from #351

@mkavulich I think only a one line change is required to get Jenkins build working so you may as well make it in this PR.
In .cicd/scripts/srw_build.sh

 # Build and install
-cd ${workspace}/test
+cd ${workspace}/tests

@danielabdi-noaa Thanks for the tip! I missed that in my search for references to the build script, I have implemented that change.
