nfs-shares may contain multiple NFS mount points

[James Page]

Hi,

We have some cases where we need to have multiple NFS shares for the same Trilio installation.
That can be either one NFS share for the OpenStack + other shares from other clouds that are also available to read; or multiple shares to write on purely simple.

Current Trilio charms do not support that.
The ongoing new charms should come with this support.

I can see on DM supports bind mounts for incremental copies [0], however we should also be able to pass multiple entries to DM config files as well.

    trilio: Support multiple NFS share configurations

    TrilioVault supports use of multiple NFS shares using a comma
    separated list. Update the ghost-nfs-share action code to
    support this type of configuration.

    The assumption is that the order of shares provided to the
    action is the same as the order of shares in the nfs-shares
    configuration option in terms of replication between sites.

    Mismatched length lists will generate an exception which can
    be propagated back to the operator.
