How to update sampleRate after calling init method?

[alexkonst]

Hi!
I want to know how i can change sampleRate option value after init of Sentry client.

Environment:

• web application (browser)
• reactjs framework
• sentry sdk (javascript)

Use cases:

• use different sampleRate for different user roles (user - 0.3, vip_user - 1) (note that we don't know user role before init method call, we get it as a result of http request to api)
• dynamically update sampleRate based on last deployment info (for example, 0-30 minutes after deploy use value 0.7, else 0.3)

I recommend using beforeSend and applying logic there: https://docs.sentry.io/platforms/javascript/configuration/options/#before-send
