Description

The purpose of this ticket is adding arguments to the CircleCI config generation script allowing to set the values specific environment variables such as DTEST_REPO or DTEST_BRANCH in the generated .circleci/config.yml file. For example, we could generate a CircleCI config file with MIDRES specifying a dtest repo and branch by running:

generate.sh -m \
  -e DTEST_REPO=git://github.com/adelapena/cassandra-dtest.git \
  -e DTEST_BRANCH=CASSANDRA-8272 

Or we could set the test multiplexer for repeating a specific test with HIGHRES:

generate.sh -h \
  -e REPEATED_UTEST_TARGET=testsome \
  -e REPEATED_UTEST_CLASS=org.apache.cassandra.cql3.ViewTest \
  -e REPEATED_UTEST_METHODS=testCompoundPartitionKey,testStaticTable \
  -e REPEATED_UTEST_COUNT=100

This can be useful on its own so we don't have to manually edit the config-2_1.yml/config.yml, and it can also be useful for automation scripts manipulating these files.
