+The java api also supports adding, modifying and removing multiple properties in a single operation:

Review Comment:
Yes - with set on an instance the become "system" level properties.
Before:
```
root@uno> config -f bloom

SCOPE | NAME | VALUE
-----------+--------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------
default | table.bloom.enabled ................ | false
default | table.bloom.error.rate ............. | 0.5%
default | table.bloom.hash.type .............. | murmur
default | table.bloom.key.functor ............ | org.apache.accumulo.core.file.keyfunctor.RowFunctor
default | table.bloom.load.threshold ......... | 1
default | table.bloom.size ................... | 1048576
default | tserver.bloom.load.concurrent.max .. | 4
-----------+--------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------
```
After:
```
jshell> import org.apache.accumulo.core.conf.Property;
jshell> client.instanceOperations().modifyProperties(properties -> {
...> properties.remove(Property.TABLE_FILE_MAX.getKey());
...> properties.put("table.bloom.enabled", "true");
