Add the ability to control event_cache_size for Synapse

Browse Source 
I've found the previous 10K default value to be way too low
on a bunch of servers I'm running, so it's now up to
100K and made configurable.

## Events cache size increase and configurability for Matrix Synapse
The playbook now lets you configure Matrix Synapse's `event_cache_size` configuration via the `matrix_synapse_event_cache_size` playbook variable.
Previously, this value was hardcoded to `"10K"`. From now on, a more reasonable default of `"100K"` is used.
## Password-peppering support for Matrix Synapse ## Password-peppering support for Matrix Synapse
The playbook now supports enabling password-peppering for increased security in Matrix Synapse via the `matrix_synapse_password_config_pepper` playbook variable. Using a password pepper is disabled by default (just like it used to be before this playbook variable got introduced) and is not to be enabled/disabled after initial setup, as that would invalidate all existing passwords.
