feat: sqlite3store context cancelation

[TobiasGleiter]

Sqlite3store context cancelation

Currently, the sqlite3store implements only not context aware funcs for example Find or Commit.

Proposal

Implement context aware funcs to handle timeouts and cancelations gracefully.

I suggest adding the following funcs:

• FindCtx(ctx context.Context, token string) ([]byte, bool, error)
• CommitCtx(ctx context.Context, token string, b []byte, expiry time.Time) error
• DeleteCtx(ctx context.Context, token string) error
• AllCtx(ctx context.Context) (map[string][]byte, error)

And altering the existing internal funcs:

• deleteExpiredCtx(ctx context.Context) error
