fix(dashmate): status command shows tenderdash error before activation

[pshenmic]

Issue being fixed or feature implemented

Tenderdash RPC is only available after a platform activation, which will happen in 3 weeks from now. Since TD RPC is used to perform healthcheck on the service, we need to an additional check for softfork activation for the mainnet network configs.

What was done?

Added a getblockchaininfo core rpc request in the status platform command
It will only query tenderdash if the mn_rr softfork is already active.
An additional status line about platform activation time was also added.

How Has This Been Tested?
