Having custom deb, rpm, pkg and msi packages to enroll nodes

[javuto]

Adding the ability to store the location for packages for Linux (RPM or DEB), Mac (PKG) or Windows (MSI). These packages can be used to enroll new nodes for a given environment. The changes apply to:

• osctrl-tls: Packages are served using the enrollment secret, same as the one-liners.
• osctrl-admin: Packages are displayed for each target platform and location can be updated via admin console.
• osctrl-cli: Added new commands to update the value for deb, rpm, pkg and msi packages per environment:

root@2bdefb74eb27:/opt/osctrl# ./bin/osctrl-cli env u --deb package.deb -n dev
✅ environment dev was updated successfully
root@2bdefb74eb27:/opt/osctrl# ./bin/osctrl-cli env u --pkg package.pkg -n dev
✅ environment dev was updated successfully
root@2bdefb74eb27:/opt/osctrl# ./bin/osctrl-cli env u --rpm package.rpm -n dev
✅ environment dev was updated successfully
root@2bdefb74eb27:/opt/osctrl# ./bin/osctrl-cli env u --msi package.msi -n dev
✅ environment dev was updated successfully
