When we add product name customization, we mistakenly defined the
parameter on each package build script.
Number of script is increasing since we recently added relocatable
python3 package, we should merge it in single place.
Also we should save the parameter on relocatable package, just like
version-release parameters.
So move the definition to SCYLLA-VERSION-GEN, save it to
build/SCYLLA-PRODUCT-FILE then archive it to relocatable package.

This patch adds the implementation for begin and finish local sampling
of a column family.
There is a difference in the implementation of Cassandra API and Scylla.
In Cassandra and the JMX an external source start and stop the sampling.
In Scylla, a single API call start the sampling and return with the
result. In Scylla the API call always return sampling of the read and of
the writes.
To bridge the difference, the begin sampling command will use a Future
when calling the API. The finish method will wait for the future to end.
Because of the different implementation, it is possible that two
consecutive calls will be made to start sampling one for the read and
one for the write, similarly, two calls will be made to finish for read
and write.
The implementation would ignore the second call to start and will
store the result, so the second call to finish will be served from the
stored result.
Note, that the use of future is only for safety, the way we expect it to
work, the caller to the begin sampling will sleep anyhow while waiting
for the result.
To avoid breaking the MBean compatibility we piggyback the duration on
top of the sampler string.
If no duration is given, a default duration will be taken, this is also
just as a precaution, we will modify the nodetool implementation to
pass that information.
There is a known issue with cardinality, that will need to be addressed.
Also we return a value in the raw column to match what Cassandra JMX
returns, but it's a duplication of the partition key.

Introduce more memory efficient version of ObjectName and use it in JMX Server.
The original version stores the same data multiple times in different forms.
Big part of data is shared by multiple instances of ObjectName.
Original class keeps a separate copy for each instance.
The new version keeps only one copy that's shared by all instances.
"
* 'speedup_1' of https://github.com/haaawk/scylla-jmx:
Introduce and use TableMetricObjectName
Ensure regular ObjectName is returned to remote callers
Use JmxMBeanServer instead of MBeanServer
Default implementation stores MBeans in the following map:
<domain name> -> (<properties as a single string> -> NamedObject)
This is problematic because NamedObject contains ObjectName that
has both domain and properties inside itself.
This means we're storing the same data twice.
For domain "" we want to store MBeans in a more compact way using map:
ObjectName -> DynamicMBean
which is equivalent to NamedObject.

This is a new extention of ObjectName that uses less memory.
TableMetricNameFactory and AllTableMetricNameFactory can

This means it won't be possible to transport it to a remote
caller. We want to keep this new object local to JMX server as well.

from APIBeanServer is transformed into a regular ObjectName.

JmxMBeanServer is a concrete implementation of a MBeanServer.
We want to use it directly because we need to bypass calls to
JmxMBeanServer.registerMBean and JmxMBeanServer.unregisterMBean.
They take ObjectName as parameter, copy it using
ObjectName.getInstance(ObjectName) and pass it to registerMBean
and unregisterMBean of JmxMBeanServer.getMBeanServerInterceptor().
We want to avoid this copy and pass the ObjectName argument directly
to JmxMBeanServer.getMBeanServerInterceptor().
To do that this patch:
1. changes all MBeanServer variables to JmxMBeanServer
2. creates JmxMBeanServer in APIBuilder making sure accessing
interceptors is allowed
3. makes sure that JmxMBeanServer.getMBeanServerInterceptor().registerMBean
is called wherever JmxMBeanServer.registerMBean was called
4. makes sure that JmxMBeanServer.getMBeanServerInterceptor().unregisterMBean
is called whenever JmxMBeanServer.unregisterMBean was called
Next patch will use different ObjectName implementation that will
use less memory and this patch is crucial because without it every ObjectName
is transformed with ObjectName.getInstance which turns the object into
a regular ObjectName.

This patch enhances the sysconfig file by adding the available options

defined. That way scylla-jmx is ran with the params defined into
/etc/defaults/scylla-jmx.
