Fix/timeout

[volodymyrZotov]

This PR fixes the issue when Client throws an error if OP_CONNECT_CLIENT_REQ_TIMEOUT env var is not set.

In addition get_timeout function is improved to cover the following cases:

• when export OP_CONNECT_CLIENT_REQ_TIMEOUT=None - it disables all the timeouts (behaves the same as described in to documentation)
• when export OP_CONNECT_CLIENT_REQ_TIMEOUT='' - it sets default timeout 5s.
• when export OP_CONNECT_CLIENT_REQ_TIMEOUT=0 -it sets default timeout 5s.

Testing steps

The env var is set

1. Up 1Password Connect server.
2. Put this to main.py file

   
   from onepasswordconnectsdk.client import AsyncClient, Client
   from onepasswordconnectsdk import new_client

client: Client = new_client(host, token) #put your token an host vaults = client.get_vaults() print(vaults)

3. `export OP_CONNECT_CLIENT_REQ_TIMEOUT=30`
4. run `python main.py`

**Should use default timeout**
1. Up 1Password Connect server.
2. Put this to `main.py` file 

from onepasswordconnectsdk.client import AsyncClient, Client from onepasswordconnectsdk import new_client

client: Client = new_client(host, token) #put your token an host vaults = client.get_vaults() print(vaults)

3. run `python main.py`

Resolves #104

Thanks for fixing this @volodymyrZotov, I've created a PR as well fixing this but you was faster than me. Sorry for the bug I've introduced :(

Fell free to close my PR in favor of yours.

@raphapassini No worries! I also missed that when tested it. Thanks for the attempt to fix it! That looks like the right approach. But I lean toward merging this one as it also covers edge cases like setting None and non-numeric values.
