Initial commit for Clover Collector

- Added a container named clover-collector using clover
container as a base with build script
- GRPC server to manage collector process
- Cassandra DB client interface to initialize visibility keyspace
- Init messaging adds table schemas for tracing - traces & spans
- Adds table for monitoring - metrics
- Does not implement Cassandra server but developed using
public Cassandra docker container
- Collector process in simple loop that periodically fetches
traces and monitoring data and inserts to Cassandra - not optimized
for batch retrieval yet for monitoring
- CLI interface added to collector process and used
by GRPC server for configuration
- Simple GRPC client script to test GRPC server and start/stop
of collector process
- Collector process can be configured with access for tracing,
monitoring and Cassandra
- Added a return value in monitoring query method

- Added ability to truncate tracing, metrics and spans tables
in cql
- Added cql prepared statements and batch insert for metrics
and spans
- Align cql connection to cql deployment within k8s
- Fix issue with cql host list using ast and collect process
args with background argument
- Added redis interface to accept service/metric list
externally for monitoring (will work in conjunction
with clover-controller)
- Use k8s DNS names and default ports for monitoring, tracing
and cassandra
- Added yaml manifest renderer/template for collector
