Add tenant commands

[elv-preethi]

Added commands to:

• add, update and show tenant_status : active, inactive or frozen.
• add, remove and show tenant groups: tenant_admin, content_admin, tenant_user_group
• add and remove tenant contract id and tenant id from given object also from account

Updated commands:

• space_tenant_create : to add tenant_contract_id, tenant_user_group and set status to active
• account_set_tenant/ account_create/ group_create: to add tenant contract id and tenant id
• tenant_show: shows status and tenant_user_group
• tenant_fix: adds tenant_user_group and adds tenant status if provided

Requires elv-client-js PR: eluv-io/elv-client-js#265

Note:
In ./elv-live command:

• provision [tenant] : shows tenant_user_group (not able to test in dev environmant, since it required mainObjects)
