Option alias '--days=NUMBER' can now be used for all other options which
indicate a validity period.
* Option: --days
This global option is an alias for one of the following:
* Expiry days for a new CA.
eg: '--days=3650 build-ca'
* Expiry days for new/renewed certificate.
eg: '--days=1095 renew server'
* Expiry days for certificate revokation list.
eg: '--days=180 gen-crl'
* Cutoff days for commands: show-expire or renewable.
eg: '--days=90 show-expire'"
The alias '--days' is now ONLY applied to the variable which requires it.
eg: If building a certificate then the appropriate variable for that type
is set. The other possible uses are not set by the same use.
