Adding support for disabling default metrics using Tyk Chart

[Kaushal_Prajapati]

Hi Asha,

I have tried that but it doesn’t seem to be working. It is still creating default metrics.

e.g.:
- name: TYK_PMP_PUMPS_PROMETHEUS_META_DISABLEDMETRICS
value: ‘[“tyk_latency_bucket”]’

Note that I am using 1.7 version for tyk pump.

Sincerely,
Kaushal
