Rename zbxpcp package

[Marko Myllynen <myllynen@xxxxxxxxxx>]

Hi,

I think we should rename the zbxpcp package (pcp-export-pcp2zabbix
currently).

The other pcp2... utilities and packages are "active" tools like
pcp2graphite, pcp2elasticsearch, pcp2hawkular, pcp2pdf. pmrep's Zabbix
output mode would also fit into this category (e.g. if we separate it
out in the future or sym link pcp2zabbix -> pmrep).

However, zbxpcp is a "passive" component used by Zabbix agent and not
usable by itself. Given this and the possibility to have an "active"
pcp2zabbix in the future, I propose we package zbxpcp in
pcp-export-zabbix-agent or such.

Thanks,
