minor bug fix

[My LinuxHAList]

Hi Devs,

I'm somewhat certain that this is a bug and not entirely sure if this
has been reported:
/usr/local/vcl/lib/VCL/Module/Provisioning/esx.pm
Line 1019:                if ($l =~ /([a-zA-Z1-9]*):\s*([-_.a-zA-Z1-9]*)/) {
should read              if ($l =~ /([a-zA-Z0-9]*):\s*([-_.a-zA-Z0-9]*)/) {

Thanks
