YANG model update/upgrade procedure

[rastislavs]

Implement the YANG model update/upgrade procedure: When there is a new version of a YANG model (with the same revision date or with a newer revision date), the datastore should allow to switch to the new model while preserving existing startup (or even running?) datastore data - if possible. If it is not possible, the incompatible data leaves should be either removed, or whole operation should be skipped.

For this we should implement a new operation of sysrepoctl, e.g. sysrepoctl --upgrade.

In the simplest case, it should do the equivalent of:

sysrepocfg --export
sysrepoctl --uninstall
sysrepoctl --install
sysrepocfg --import

support for this (or very similar) functionality is also requested from libyang, see CESNET/libyang#231

Latest sysrepo supports this.
