Stop alertmanager to fetch inhibited alerts

Default query for fetching alerts from alertmanager, fetches inhibited alerts also.
By the logic behind the inhibition, there is no need to fetch this alerts.
In this PR I have changed the inhibited query string param to false to filter out inhibited alerts.

Sorry for the late reply - as I do not use Alertmanager: what are inhibited alerts?

Hi
No problem
Inhibited alerts are alerts that are muted by other alerts. For example if cpu usage more that 80% is warning, and more than 90% is critical, when cpu usage goes above 90% both warning and critical alerts will fire.
In alertmanager you can inhibit warning alert by critical alert, so when you set inhibited=false, you will not get inhibited alerts in output.
