Migrate Parquet Jira issues to GitHub

[asfimport]

Parquet community discussed and decided (parquet-*, parquet-cpp) to migrate issue tracking from ASF Jira to issue tracker to GitHub issue trackers of individual Apache Parquet repositories with the following component mapping:

jira/parquet-avro --> github/parquet-java
jira/parquet-cascading --> github/parquet-java
jira/parquet-cli --> github/parquet-java
jira/parquet-cpp --> github/arrow
jira/parquet-format --> github//parquet-format
jira/parquet-hadoop --> github//parquet-java
jira/parquet-mr --> github/parquet-java
jira/parquet-pig --> github/parquet-java
jira/parquet-protobuf --> github/parquet-java
jira/parquet-site --> github/parquet-site
jira/parquet-testing --> github/parquet-testing
jira/parquet-thrift --> github/parquet-java 

Approximate migration script that will be applied was used for Apache Arrow migration and can be found here. For more details on decisions that were made there in migration design see Arrow migration issue.
