This was IZ 1812 in project gridengine.

In certain setups, a host_alias file is required.
For example, in our performance test cluster, the master host has multiple
network interfaces with different hostnames configured.

In such cases, tests like the tight_integration test will fail, as execd commlib
will reject qrsh -inherit calls coming from the master host, as master host and
exec hosts resolve the master host differently.

Using a host alias file solves this issue.

Testsuite could handle such cases as follows:
- the testsuite host configuration contains "host_alias" entries per host
- testsuite installation will lookup the host configuration for each host being
part of the cluster. If a host contains such host_alias entries, a host_alias
file will be created before installation.
