Fix a high memory consumption that also is part of the issue pokt-network#1457.
Under high load of requests (1000/rps or more) the RAM got crazy and scale up to 40GB or close to that.
Now after the fix of pokt-network#1457 with the worker pool, the node remains under 14gb of ram in my local tests.

… keep cpu in high load.

* Fixed RPC timeout handled as Seconds instead of Milliseconds
* Updated mesh.md to handle new cache configurations
* Updated mesh.md to list /v1/private/mesh/session as required on the whitelist endpoints/paths

* Fixed /v1/private/mesh/updatechains to properly update them on memory and disk
* Added hot reload for servicer private key files (add & remove)
  * on add turn on the checks and start allowing it
  * on remove stop receiving and consume all the pending relays in queue
* Version bump

* Enhanced log about missing sessions
* Version Bump

…rivate key is removed after it been supported by the mesh node.

…ral solution)

* Fixed error that panic process when load servicer_url without http/https schema. Now it will properly report the error.
* Added manual cron to compact relays database every hour.
* Removed a log2.Fatal that was crashing the process.

* relay_cache_background_sync_interval was not used
* relay_cache_background_compaction_interval was not used

Added:
* hot_reload_interval allow to turn off using 0 the hot reload of chains/servicers - otherwise the amount of MS it will check the files again

Updated:
* Now health check of servicers is done every 60s - was 30s - future: will be configurable through config.json
* Now old sessions are evaluated to be removed every 30m - was 30s - future: will be configurable through config.json
* config.json example of docs.

Removed:
* Manual relays db compaction job removed; We receive reports that it was corrupting relays database if you run at same time of background configured by relay_cache_background_compaction_interval
