Adding new APIs /column_family/tombstone_gc and /storage_service/tombstone_gc, that will allow for disabling tombstone garbage collection (GC) in compaction.
Mimicks existing APIs /column_family/autocompaction and /storage_service/autocompaction.
column_family variant must specify a single table only, following existing convention.
whereas the storage_service one can specify an entire keyspace, or a subset of a tables in a keyspace.
column_family API usage
-----
```
The table name must be in keyspace:name format
Get status:
curl -s -X GET "http://127.0.0.1:10000/column_family/tombstone_gc/ks:cf"
Enable GC
curl -s -X POST "http://127.0.0.1:10000/column_family/tombstone_gc/ks:cf"
Disable GC
curl -s -X DELETE "http://127.0.0.1:10000/column_family/tombstone_gc/ks:cf"
```
storage_service API usage
-----
```
Tables can be specified using a comma-separated list.
Enable GC on keyspace
curl -s -X POST "http://127.0.0.1:10000/storage_service/tombstone_gc/ks"
Disable GC on keyspace
curl -s -X DELETE "http://127.0.0.1:10000/storage_service/tombstone_gc/ks"
Enable GC on a subset of tables
curl -s -X POST
"http://127.0.0.1:10000/storage_service/tombstone_gc/ks?cf=table1,table2"
```
