Curator: Document OpenSSL 1.0.2 requirement for Curator 5.4

[ppf2]

Somewhere between 5.0 -> 5.4 version of curator, it started requiring OpenSSL 1.0.2 libraries for it to work on Centos/RHEL environments.

Would be helpful to document this accordingly.

I will add this dependency to the RPM package, rather than merely document it.

I can confirm that in Red Hat 7.0 this happens even when downgrading to Curator 5.3. Upgrading the openssl library version to 1.0.2 is a must. The documentation needs to also be updated

i have the same issue, workaround if needed (updating "openssl-libs" package):
$sudo yum update openssl-libs

The dependency has been addressed in the build scripts.
