feat: support IgnoreTransactions client option

[greywolve]

Adds support for ignoring transactions by using the IgnoreTransactions client option. This requires a slice of regex strings that are matched against a transaction's name. If there's a match the transaction is dropped.

Fixes #628

LGTM, thanks 👍

Could you just add a bit of PR description and link to the issue it's fixing/implementing?

We want to make sure this continues to work with the ignoreErrorsIntegration that is currently controlled via the IgnoreErrors option.

I suggest adding an ignoreTransactionsIntegration, as we can't remove the ignoreErrorsIntegration, which would cause issues for people using it today.

Hmm, my bad. I missed that IgnoreErrors was already a working integration. I'll rework this to just add an IgnoreTransaction integration, and not do any of the logic in client.go.

@cleptric rework done. :)
