Bug #34284	Enterprise Manager - agent installer unable to veryfy hostname / IP address

Description:
When agent is installed on a server with multiple IP aliases, installer fails to verify IP address. The server is running with 10+ IP aliases (all of them properly in DNS). Separate mysqld process is binded to each virtual IP.

How to repeat:
[root@dc01mdb-01 ~]# ./mysqlserviceagent-1.2.0.7879-linux-x86_64-glibc2.3-installer.bin

Suggested fix:
make the validation understand the virtual addresses

Workaround
 - If you enter IP address instead of hostname, installer will properly verify it

Workaround1
 - if you do skip the verification the agent will work properly with the hostname
