…elastic#9784) In Vsphere module, some fields returned by the Vsphere library contain pointers to some values that could potentially be nil. With this PR, we do a nil-check prior every access to any of those fields to avoid their writing in case they are nil and protecting Metricbeat from panicking. (cherry picked from commit 7c31ced)

Cherry-pick of PR #9784 to 6.6 branch. Original message:
It seems that some fields within the vsphere module on Metricbeat are pointers where the
nilcheck access is not being done. This can cause panics that are not easy to reproduce.This PR checks every pointer that acces a pointer from the
gvmomilibrary which is used to access vsphere data.Initially, we only know about panics in the
virtualmachinemetricset but I have seen that thehostmetricset could potentially have the same problem
